Built-in Generation Functions

Overview

The Generate class uses callback functions to produce output that matches your needs. You write your own python functions or reuse one of the functions built-in to support the pre-defined styles.

Calling SetStyle() with a name below configures a series of callbacks to produce that output. You can further adjust the output by replacing callbacks with SetEventFn(), SetTypeFn(), or SetOtherFn().

Styles

apt: APT program. Moves are converted into GOTO commands with appropriate FEDRAT, RAPID, and SPINDL modifiers. Tool changes are declared with the TLDATA/MILL style command used by NX.
crcl: Canonical Robot Command Language, a low level XML robot command format. The output does linear moves and simulated probing operations.
dmis: DMIS program that declares the datums defined by the STEP model and an inspection plan using the probing operations defined in the model. The output also declares the features for the geometry associated with the probing operations, so a group of probes on a cylindrical surface will be declared with a FEAT/CYLNDR and a MEAS/CYLNDR block. Similarly for FEAT/PLANE.
dmis-cnc: Alias for the "dmis" style
dmis-manual: Same as the "dmis", but starts with MODE/MAN rather than MODE/PROG,MAN.
esab-cut: ESAB Plate Cutting with a plasma torch. One of three styles of output generated from STEP-NC process for plasma cutting and laser marking on ESAB controls. This was used by an NSRP project to explore STEP-NC for steel processing in shipbuilding.
esab-farmark: ESAB Farside Mark with laser. See above.
esab-nearmark: ESAB Nearside Mark with laser. See above.
fanuc: General FANUC program style. Program uses the GetProgramNumber() value in the header declaration. Will use TCP mode G43.5 and command IJK for five axis moves. Uses Renishaw inspection-plus macros for probing.
haas: General Haas program style. Based on the FANUC style but has Haas codes for through-spindle coolant. Uses Renishaw inspection-plus macros for probing.
heidenhain: General Heidenhain program style. Forces all lines to have block numbers. Use one of the variants below for five axis programs.
heidenhain-ac: Heidenhain variation for AC machines. Uses M128 and commands A/C for five axis moves.
heidenhain-bc: Heidenhain variation for BC machines. Uses M128 and commands B/C for five axis moves.
mdsi: MDSI program style for a left-handed lathe. This was used for early turning tests. It sets the destination transform to place everything into the ZX plane and reverse arc directions for the left-handed lathe.
okuma: General Okuma program style. Use one of the variants below for five axis programs.
okuma-ac: Okuma variation for AC machines. Uses G169 and commands A/C for five axis moves.
okuma-bc: Okuma variation for BC machines. Uses G169 and commands B/C for five axis moves.
okuma-omac: Okuma variation with OMAC macros for spindle and other fuctions.
siemens: General Siemens program style. This uses TRAORI with A3/B3/C3 commands for five axis motion and the native CYCLE978 for XY probing. It also uses OMAC macros for spindle and other fuctions.
siemens-810: Siemens variation that does not use any macros
siemens-dmdii: Siemens variation that uses Renishaw inspection plus macros and TRAORI, but commands the AC axes.
siemens-nist: Siemens variation that uses G700 to set units rather than G70.
siemens-renishaw: Siemens variation that uses Renishaw inspection plus macros.
siemens-traori: Siemens variation that explicitly calls TRAORI setup rather than expecting it to be done using OMAC macros.

Predefined Generation Functions

The built-in functions below use the common function prototype, which takes a generate, state vars, and a cursor object, then returns a string. These functions handle the details of the built-in styles.

delegate System::String GenerateFn(
	Generate gen,
	GenerateState gs,
	Adaptive cur
	);

All builtin functions are declared static on the Generate class. Some functions handle events via SetEventFn(), others handle specific types of process elements via SetTypeFn(), but most are used with SetOtherFn() to provide partial strings for assembling a complete response for an event.

Generate.builtin_workingstep_start_fanuc_unwind(): If we have just done a tool change the position is unknown and we do not need to unwind. If the position is known, rapid up to security plane with IJK of 001, then emit G49 G53C360, and then put the control back into TCP mode with G43.5HnumI0J0K1. Call builtin_workingstep_start_default to do usual initialization.
Generate.builtin_workingstep_start_siemens(): Emit STOPRE to keep command lookahead from executing variable assignment early, then set the STPWS= variable to the current workingstep index.
Generate.builtin_workingstep_trace_clear_fanuc(): Set variable #185=0.
Generate.builtin_workingstep_trace_clear_siemens(): Set the STPWS= variable to its base value.
Generate.builtin_workoffset_default(): Default for "workoffset" function. Return G53 if offset is zero, or G54-58 for offsets 1-5.
Generate.builtin_workoffset_okuma(): Return G15 H0 if offset is zero, or G15 H1-200 for offsets 1-200.
Generate.builtin_workplan_end_default(): Default for the CtlEvent.WORKPLAN_END event. Call workplan-probe-end if the workplan contains probing operations.
