Function Documentation

void rs274ngc_line_text (  char *    line_text,
int    max_size
) 
 

copy the text of the most recently read line into the line_text array, but stop at max_size if the text is longer.

Canonical "Do it" functions

This is a set of dummy definitions for the canonical machining functions given in canon.hh. These functions just print themselves and, if necessary, update the dummy world model. On each output line is printed: 1. an output line number (sequential, starting with 1). 2. an input line number read from the input (or ... if not provided). 3. a printed representation of the function call which was made.

If an interpreter which makes these calls is compiled with this set of definitions, it can be used as a translator by redirecting output from stdout to a file.

Parameters:
line_text  ARGUMENTS
max_size  string: to copy line into

void SET_FEED_REFERENCE (  CANON_FEED_REFERENCE    reference ) 
 

SET_FEED_RATE sets the feed rate that will be used when the spindle is told to move at the currently set feed rate. The rate is either: 1. the rate of motion of the tool tip in the workpiece coordinate system, which is used when the feed_reference mode is "CANON_WORKPIECE", or 2. the rate of motion of the tool tip in the XYZ axis system, ignoring motion of other axes, which is used when the feed_reference mode is "CANON_XYZ".

The units of the rate are:

1. If the feed_reference mode is CANON_WORKPIECE: length units (inches or millimeters according to the setting of CANON_UNITS) per minute along the programmed path as seen by the workpiece.

2. If the feed_reference mode is CANON_XYZ: A. For motion including one rotational axis only: degrees per minute. B. For motion including two rotational axes only: degrees per minute In this case, the rate applies to the axis with the larger angle to cover, and the second rotational axis rotates so that it has always completed the same proportion of its required motion as has the rotational axis to which the feed rate applies. C. For motion involving one or more of the XYZ axes (with or without simultaneous rotational axis motion): length units (inches or millimeters according to the setting of CANON_UNITS) per minute along the programmed XYZ path.

void SET_MOTION_CONTROL_MODE (  CANON_MOTION_MODE    mode ) 
 

This sets the feed_reference mode to either CANON_WORKPIECE or CANON_XYZ.

The CANON_WORKPIECE mode is more natural and general, since the rate at which the tool passes through the material must be controlled for safe and effective machining. For machines with more than the three standard XYZ axes, however, computing the feed rate may be time-consuming because the trajectories that result from motion in four or more axes may be complex. Computation of path lengths when only XYZ motion is considered is quite simple for the two standard motion types (straight lines and helical arcs).

Some programming languages (rs274kt, in particular) use CANON_XYZ mode. In these languages, the task of dealing with the rate at which the tool tip passes through material is pushed back on the NC-program generator, where the computation of path lengths is (almost always in 1995) an off-line activity where speed of calculation is not critical.

In CANON_WORKPIECE mode, some motions cannot be carried out as fast as the programmed feed rate would require because axis motions tend to cancel each other. For example, an arc in the YZ-plane can exactly cancel a rotation around the A-axis, so that the location of the tool tip with respect to the workpiece does not change at all during the motion; in this case, the motion should take no time, which is impossible at any finite rate of axis motion. In such cases, the axes should be moved as fast as possible consistent with accurate machining.

It would be possible to omit the SET_FEED_REFERENCE command from the canonical commands and operate always in one mode or the other, letting the interpreter issue SET_FEED_RATE commands, if necessary to compensate if the NC language being interpreted used the other mode.

This would create two disadvantages when the feed_reference mode assumed by the canonical commands differed from that assumed by the NC language being interpreted:

1. The output code could have a lot of SET_FEED_RATE commands not found in the input code; this is a relatively minor consideration.

2. If the interpreter reads a program in language which uses the CANON_XYZ mode and writes canonical commands in the CANON_WORKPIECE mode, both the interpreter and the executor of the output canonical commands would have to perform a lot of complex calculations. With the SET_FEED_REFERENCE command available, both do only simple calculations for the same motions.

void SELECT_TOOL (  int    slot ) 
 

It is assumed that each cutting tool in the machine is assigned to a slot (intended to correspond to a slot number in a tool carousel). This command results in the tool currently in the spindle (if any) being returned to its slot, and the tool from the slot designated by slot_number (if any) being inserted in the spindle.

If there is no tool in the slot designated by the slot argument, there will be no tool in the spindle after this command is executed and no error condition will result in the controller. Similarly, if there is no tool in the spindle when this command is given, no tool will be returned to the carousel and no error condition will result in the controller, whether or not a tool was previously selected in the program.

It is expected that when the machine tool controller is initialized, the designated slot for a tool already in the spindle will be established. This may be done in any manner deemed fit, including (for, example) recording that information in a persistent, crash-proof location so it is always available from the last time the machine was run, or having the operator enter it. It is expected that the machine tool controller will remember that information as long as it is not re-initialized; in particular, it will be remembered between programs.

For the purposes of this command, the tool includes the tool holder.

For machines which can carry out a select_tool command separately from a change_tool command, the select_tool command must have been given before the change_tool command, and the value of slot must be the slot number of the selected tool.
