rs274ngc.cc
This rs274ngc.cc file contains the source code for (1) the kernel of several rs274ngc interpreters and (2) two of the four sets of interface functions declared in canon.hh: 1. interface functions to call to tell the interpreter what to do. These all return a status value. 2. interface functions to call to get information from the interpreter.
Kernel functions call each other. A few kernel functions are called by interface functions.
Interface function names all begin with "rs274ngc_".
Error handling is by returning a status value of either a non-error code (RS274NGC_OK, RS274NGC_EXIT, etc.) or some specific error code from each function where there is a possibility of error. If an error occurs, processing is always stopped, and control is passed back up through the function call hierarchy to an interface function; the error code is also passed back up. The stack of functions called is also recorded. The external program calling an interface function may then handle the error further as it sees fit.
Since returned values are usually used as just described to handle the possibility of errors, an alternative method of passing calculated values is required. In general, if function A needs a value for variable V calculated by function B, this is handled by passing a pointer to V from A to B, and B calculates and sets V.
There are a lot of functions named read_XXXX. All such functions read characters from a string using a counter. They all reset the counter to point at the character in the string following the last one used by the function. The counter is passed around from function to function by using pointers to it. The first character read by each of these functions is expected to be a member of some set of characters (often a specific character), and each function checks the first character.
This version of the interpreter not saving input lines. A list of all lines will be needed in future versions to implement loops, and probably for other purposes.
This version does not use any additional memory as it runs. No memory is allocated by the source code.
This version does not suppress superfluous commands, such as a command to start the spindle when the spindle is already turning, or a command to turn on flood coolant, when flood coolant is already on. When the interpreter is being used for direct control of the machining center, suppressing superfluous commands might confuse the user and could be dangerous, but when it is used to translate from one file to another, suppression can produce more concise output. Future versions might include an option for suppressing superfluous commands.
This file has been arranged typographically so that it may be used for compiling fifteen different executables. The file may be compiled as is for a six-axis interpreter. The file may be pre-preprocessed into "pre.cc" by "prepre" (a lex-based pre-processor). All fifteen executables may be compiled from the pre.cc file. The special typography items are:
1. Any line with the comment /^AA^/, /^BB^/, or /^CC^/ at the end (where ^ is replaced by *).
2. Calls to the canonical functions STRAIGHT_FEED, STRAIGHT_TRAVERSE, STRAIGHT_PROBE, and ARC_FEED. These are always set on two lines with the rotary axes on the second line:
3. Calls to the canonical function SET_ORIGIN_OFFSETS. These are always set on six lines, with one argument per line.
4. Anywhere else AA, BB, or CC appears followed by an underscore.
The pre-preprocessor looks for these items of typography and, in the output file (pre.cc), resets them appropriately marked with ifdef and endif. The rest of the text is put into the output file unchanged.
The compiler flags are:
1. -DAA to have an A-axis
2. -DBB to have a B-axis
3. -DCC to have a C-axis
4. -DALL_AXES to have a 3-, 4-, or 5-axis interpreter use all three rotary axes in canonical function calls. In those calls, the value for a rotary axis not compiled into an interpreter is always zero.
5. -DAXIS_ERROR to have a 3-, 4-, or 5-axis interpreter signal an error if the input RS274 code has a value for an axis not compiled in. If this flag is not used, the interpreter will read and ignore values for axes not compiled in.

#define ERM ( error_code )

Value:
if (1) { \ _setup.stack_index SET_TO 0; \ strcpy(_setup.stack[_setup.stack_index++], name); \ _setup.stack[_setup.stack_index][0] SET_TO 0; \ return error_code; \ } else
The _setup model includes a stack array for the names of function calls. This stack is written into if an error occurs. Just before each function returns an error code, it writes its name in the next available string, initializes the following string, and increments the array index. The following four macros do the work.
The size of the stack array is 50. An error in the middle of a very complex expression would cause the ERP and CHP macros to write past the bounds of the array if a check were not provided. No real program would contain such a thing, but the check is included to make the macros totally crash-proof. If the function call stack is deeper than 49, the top of the stack will be missing.

convert_cycle_g83
Returned Value: int (RS274NGC_OK)
Side effects: See below
Called by: convert_cycle_xy convert_cycle_yz convert_cycle_zx
For the XY plane, this implements the following RS274/NGC cycle, which is usually peck drilling: 1. Move the z-axis only at the current feed rate downward by delta or to the specified bottom_z, whichever is less deep. 2. Rapid back out to the clear_z. 3. Rapid back down to the current hole bottom, backed off a bit. 4. Repeat steps 1, 2, and 3 until the specified bottom_z is reached. 5. Retract the z-axis at traverse rate to clear_z.
CYCLE_MACRO has positioned the tool at (x, y, r, a, b, c) when this starts.
The rapid out and back in causes any long stringers (which are common when drilling in aluminum) to be cut off and clears chips from the hole.
For the XZ and YZ planes, this makes analogous motions.

Side effects: A number of moves are made to execute the g-code
Called by: convert_cycle
The function does not require that any of x,y,z, or r be specified in the block, except that if the last motion mode command executed was not the same as this one, the r-value and z-value must be specified.
This function is handling the repeat feature of RS274/NGC, wherein the L word represents the number of repeats [NCMS, page 99]. We are not allowing L=0, contrary to the manual. We are allowing L > 1 in absolute distance mode to mean "do the same thing in the same place several times", as provided in the manual, although this seems abnormal.
In incremental distance mode, x, y, and r values are treated as increments to the current position and z as an increment from r. In absolute distance mode, x, y, r, and z are absolute. In g87, i and j will always be increments, regardless of the distance mode setting, as implied in [NCMS, page 98], but k (z-value of top of counterbore) will be an absolute z-value in absolute distance mode, and an increment (from bottom z) in incremental distance mode.
If the r position of a cycle is above the current_z position, this retracts the z-axis to the r position before moving parallel to the XY plane.
In the code for this function, there is a nearly identical "for" loop in every case of the switch. The loop is the done with a compiler macro, "CYCLE_MACRO" so that the code is easy to read, automatically kept identical from case to case and, and much shorter than it would be without the macro. The loop could be put outside the switch, but then the switch would run every time around the loop, not just once, as it does here. The loop could also be placed in the called functions, but then it would not be clear that all the loops are the same, and it would be hard to keep them the same when the code is modified. The macro would be very awkward as a regular function because it would have to be passed all of the arguments used by any of the specific cycles, and, if another switch in the function is to be avoided, it would have to passed a function pointer, but the different cycle functions have different arguments so the type of the pointer could not be declared unless the cycle functions were re-written to take the same arguments (in which case most of them would have several unused arguments).
The motions within the CYCLE_MACRO (but outside a specific cycle) are a straight traverse parallel to the selected plane to the given position in the plane and a straight traverse of the third axis only (if needed) to the r position.
The CYCLE_MACRO is defined here but is also used in convert_cycle_yz and convert_cycle_zx. The variables aa, bb, and cc are used in CYCLE_MACRO and in the other two functions just mentioned. Those variables represent the first axis of the selected plane, the second axis of the selected plane, and third axis which is perpendicular to the selected plane. In this function aa represents x, bb represents y, and cc represents z. This usage makes it possible to have only one version of each of the cycle functions. The cycle_traverse and cycle_feed functions help accomplish this.
The height of the retract move at the end of each repeat of a cycle is determined by the setting of the retract_mode: either to the r position (if the retract_mode is R_PLANE) or to the original z-position (if that is above the r position and the retract_mode is not R_PLANE). This is a slight departure from [NCMS, page 98], which does not require checking that the original z-position is above r.
The rotary axes may not move during a canned cycle.

#define MAX_STACK 5

The following version is stack-based and fully general. It is the classical stack-based version with left-to-right evaluation of operations of the same precedence. Separate stacks are used for operations and values, and the stacks are made with arrays rather than lists, but those are implementation details. Pushing and popping are implemented by increasing or decreasing the stack index.
Additional levels of precedence may be defined easily by changing the precedence function. The size of MAX_STACK should always be at least as large as the number of precedence levels used. We are currently using four precedence levels (for right-bracket, plus-like operations, times-like operations, and power).

convert_arc_comp1
Returned Value: int If arc_data_comp_ijk or arc_data_comp_r returns an error code, this returns that code. Otherwise, it returns RS274NGC_OK.
Side effects: This executes an arc command at feed rate. It also updates the setting of the position of the tool point to the end point of the move.
Called by: convert_arc.
This function converts a helical or circular arc, generating only one arc. The axis must be parallel to the z-axis. This is called when cutter radius compensation is on and this is the first cut after the turning on.
The arc which is generated is derived from a second arc which passes through the programmed end point and is tangent to the cutter at its current location. The generated arc moves the tool so that it stays tangent to the second arc throughout the move.
Parameters:

move ARGUMENTS

block either G_2 (cw arc) or G_3 (ccw arc)

settings pointer to a block of RS274/NGC instructions

end_x pointer to machine settings

end_y x-value at end of programmed (then actual) arc

Returned Value: int If arc_data_ijk or arc_data_r returns an error code, this returns that code. If any of the following errors occurs, this returns the error code shown. Otherwise, it returns RS274NGC_OK. 1. A concave corner is found: NCE_CONCAVE_CORNER_WITH_CUTTER_RADIUS_COMP 2. The tool will not fit inside an arc: NCE_TOOL_RADIUS_NOT_LESS_THAN_ARC_RADIUS_WITH_COMP
Side effects: This executes an arc command feed rate. If needed, at also generates an arc to go around a convex corner. It also updates the setting of the position of the tool point to the end point of the move. If inverse time feed rate mode is in effect, the feed rate is reset.
Called by: convert_arc.
This function converts a helical or circular arc. The axis must be parallel to the z-axis. This is called when cutter radius compensation is on and this is not the first cut after the turning on.
If one or more rotary axes is moved in this block and an extra arc is required to go around a sharp corner, all the rotary axis motion occurs on the main arc and none on the extra arc. An alternative might be to distribute the rotary axis motion over the extra arc and the programmed arc in proportion to their lengths.
If the Z-axis is moved in this block and an extra arc is required to go around a sharp corner, all the Z-axis motion occurs on the main arc and none on the extra arc. An alternative might be to distribute the Z-axis motion over the extra arc and the main arc in proportion to their lengths.

convert_straight_comp1
Returned Value: int If any of the following errors occur, this returns the error shown. Otherwise, it returns RS274NGC_OK. 1. The side is not RIGHT or LEFT: NCE_BUG_SIDE_NOT_RIGHT_OR_LEFT 2. The destination tangent point is not more than a tool radius away (indicating gouging): NCE_CUTTER_GOUGING_WITH_CUTTER_RADIUS_COMP 3. The value of move is not G_0 or G_1 NCE_BUG_CODE_NOT_G0_OR_G1
Side effects: This executes a STRAIGHT_MOVE command at cutting feed rate or a STRAIGHT_TRAVERSE command. It also updates the setting of the position of the tool point to the end point of the move and updates the programmed point. If INVERSE_TIME feed rate mode is in effect, it resets the feed rate.
Called by: convert_straight.
This is called if cutter radius compensation is on and settings->program_x is UNKNOWN, indicating that this is the first move after cutter radius compensation is turned on.
The algorithm used here for determining the path is to draw a straight line from the destination point which is tangent to a circle whose center is at the current point and whose radius is the radius of the cutter. The destination point of the cutter tip is then found as the center of a circle of the same radius tangent to the tangent line at the destination point.
Parameters:

Returned Value: int If any of the following errors occur, this returns the error shown. Otherwise, it returns RS274NGC_OK. 1. The compensation side is not RIGHT or LEFT: NCE_BUG_SIDE_NOT_RIGHT_OR_LEFT 2. A concave corner is found: NCE_CONCAVE_CORNER_WITH_CUTTER_RADIUS_COMP
Side effects: This executes a STRAIGHT_FEED command at cutting feed rate or a STRAIGHT_TRAVERSE command. It also generates an ARC_FEED to go around a corner, if necessary. It also updates the setting of the position of the tool point to the end point of the move and updates the programmed point. If INVERSE_TIME feed mode is in effect, it also calls SET_FEED_RATE and resets the feed rate in the machine model.
Called by: convert_straight.
This is called if cutter radius compensation is on and settings->program_x is not UNKNOWN, indicating that this is not the first move after cutter radius compensation is turned on.
The algorithm used here is: 1. Determine the direction of the last motion. This is done by finding the direction of the line from the last programmed point to the current tool tip location. This line is a radius of the tool and is perpendicular to the direction of motion since the cutter is tangent to that direction. 2. Determine the direction of the programmed motion. 3. If there is a convex corner, insert an arc to go around the corner. 4. Find the destination point for the tool tip. The tool will be tangent to the line from the last programmed point to the present programmed point at the present programmed point. 5. Go in a straight line from the current tool tip location to the destination tool tip location.
This uses an angle tolerance of TOLERANCE_CONCAVE_CORNER (0.01 radian) to determine if: 1) an illegal concave corner exists (tool will not fit into corner), 2) no arc is required to go around the corner (i.e. the current line is in the same direction as the end of the previous move), or 3) an arc is required to go around a convex corner and start off in a new direction.
If a rotary axis is moved in this block and an extra arc is required to go around a sharp corner, all the rotary axis motion occurs on the arc. An alternative might be to distribute the rotary axis motion over the arc and the straight move in proportion to their lengths.
If the Z-axis is moved in this block and an extra arc is required to go around a sharp corner, all the Z-axis motion occurs on the straight line and none on the extra arc. An alternative might be to distribute the Z-axis motion over the extra arc and the straight line in proportion to their lengths.
This handles inverse time feed rates by computing the length of the compensated path.
This handles the case of there being no XY motion.
This handles G0 moves. Where an arc is inserted to round a corner in a G1 move, no arc is inserted for a G0 move; a STRAIGHT_TRAVERSE is made from the current point to the end point. The end point for a G0 move is the same as the end point for a G1 move, however.
Parameters:

int find_ends ( block_pointer block,

setup_pointer settings,

double * px,

double * py,

double * pz

) [static]

find_ends
Returned Value: int (RS274NGC_OK)
Side effects: The values of px, py, pz, aa_p, bb_p, and cc_p are set
Called by: convert_arc convert_home convert_probe convert_straight
This finds the coordinates of a point, "end", in the currently active coordinate system, and sets the values of the pointers to the coordinates (which are the arguments to the function).
In all cases, if no value for the coodinate is given in the block, the current value for the coordinate is used. When cutter radius compensation is on, this function is called before compensation calculations are performed, so the current value of the programmed point is used, not the current value of the actual current_point.
There are three cases for when the coordinate is included in the block:
1. G_53 is active. This means to interpret the coordinates as machine coordinates. That is accomplished by adding the two offsets to the coordinate given in the block.
2. Absolute coordinate mode is in effect. The coordinate in the block is used.
3. Incremental coordinate mode is in effect. The coordinate in the block plus either (i) the programmed current position - when cutter radius compensation is in progress, or (2) the actual current position.
Parameters:

block ARGUMENTS

settings pointer to a block of RS274/NGC instructions

px pointer to machine settings

py pointer to end_x

pz pointer to end_y pointer to end_z

) [static]

find_straight_length
Returned Value: double (length of path between start and end points)
Side effects: none
Called by: inverse_time_rate_straight inverse_time_rate_as
This calculates a number to use in feed rate calculations when inverse time feed mode is used, for a motion in which X,Y,Z,A,B, and C each change linearly or not at all from their initial value to their end value.
This is used when the feed_reference mode is CANON_XYZ, which is always in rs274NGC.
If any of the X, Y, or Z axes move or the A-axis, B-axis, and C-axis do not move, this is the length of the path relative to the XYZ axes from the first point to the second, and any rotary axis motion is ignored. The length is the simple Euclidean distance.
The formula for the Euclidean distance "length" of a move involving only the A, B and C axes is based on a conversation with Jim Frohardt at Boeing, who says that the Fanuc controller on their 5-axis machine interprets the feed rate this way. Note that if only one rotary axis moves, this formula returns the absolute value of that axis move, which is what is desired.
Parameters:

x2 ARGUMENTS

y2 X-coordinate of end point

z2 Y-coordinate of end point

x1 Z-coordinate of end point

y1 X-coordinate of start point

z1 Y-coordinate of start point Z-coordinate of start point

This function resets the parts of the _setup model having to do with reading and interpreting one line. It does not affect the parts of the model dealing with a file being open; rs274ngc_open and rs274ngc_close do that.
There is a hierarchy of resetting the interpreter. Each of the following calls does everything the ones above it do.

const int _gees[] [static]

Interpreter global arrays for g_codes and m_codes. The nth entry in each array is the modal group number corresponding to the nth code. Entries which are -1 represent illegal codes. Remember g_codes in this interpreter are multiplied by 10.
The modal g groups and group numbers defined in [NCMS, pages 71 - 73] (see also [Fanuc, pages 43 - 45]) are used here, except the canned cycles (g80 - g89), which comprise modal g group 9 in [Fanuc], are treated here as being in the same modal group (group 1) with the straight moves and arcs (g0, g1, g2,g3). [Fanuc, page 45] says only one g_code from any one group may appear on a line, and we are following that rule. The straight_probe move, g38.2, is in group 1; it is not defined in [NCMS].
Some g_codes are non-modal (g4, g10, g28, g30, g53, g92, g92.1, g92.2, and g92.3 here - many more in [NCMS]). [Fanuc] and [NCMS] put all these in the same group 0, so we do also. Logically, there are two subgroups, those which require coordinate values (g10, g28, g30, and g92) and those which do not (g4, g53, g92.1, g92.2, and g92.3). The subgroups are identified by itemization when necessary.
Those in group 0 which require coordinate values may not be on the same line as those in group 1 (except g80) because they would be competing for the coordinate values. Others in group 0 may be used on the same line as those in group 1.
A total of 52 G-codes are implemented.
The groups are: group 0 = {g4,g10,g28,g30,g53,g92,g92.1,g92.2,g92.3} - NON-MODAL dwell, setup, return to ref1, return to ref2, motion in machine coordinates, set and unset axis offsets group 1 = {g0,g1,g2,g3,g38.2,g80,g81,g82,g83,g84,g85,g86,g87,g88,g89} - motion group 2 = {g17,g18,g19} - plane selection group 3 = {g90,g91} - distance mode group 5 = {g93,g94} - feed rate mode group 6 = {g20,g21} - units group 7 = {g40,g41,g42} - cutter diameter compensation group 8 = {g43,g49} - tool length offset group 10 = {g98,g99} - return mode in canned cycles group 12 = {g54,g55,g56,g57,g58,g59,g59.1,g59.2,g59.3} - coordinate system group 13 = {g61,g61.1,g64} - control mode

Modal groups and modal group numbers for M codes are not described in [Fanuc]. We have used the groups from [NCMS] and added M60, as an extension of the language for pallet shuttle and stop. This version has no codes related to axis clamping.
