INTRODUCTION TO FIL MACRO LANGUAGE :Basic FIL Techniques

Always start your FIL file with a standard header :

DMY=POSTF(24,1) $$ debug optionsPRINT/ON REDEF/ON $$ Allow redefinition of Var.$$ AddressesA=1;B=2;C=3;D=4;E=5;F=6;G=7;H=8;I=9;J=10;K=11;L=12M=13;N=14O=15;P=16;Q=17;R=18;S=19;T=20;U=21;V=22;W=23;X=24;Y=25;Z=26

Output something at the beginning of the program

CIMFIL/ON,MACHIN$$ nothing is ouputed to the tape before the $$ MACHIN statement is processedXX=POSTF(13) $$ Process… do what you want to do here ...CIMFIL/OFF

Debugging a post-processorDebugging a post-processor

To debug the post-processor you need to use the Listing file generated by GPOST (extension .LST )

In Pro/NC run the PP with the TRACE option to trace the CL records in the listing file

In Pro/NC-GPOST Optfile set the listing column display to non modal

In FIL set the trace options PRINT/ON : trace the macro lines in the listing file DMY=POSTF(24,1) : print FIL ISN numbers, this will help

you to find the FIL line creating the problem

When the post-processor is ready for Production put the following commands in the FIL header to minimize the size of the FIL file :

PRINT/OFF,IN ; DMY=POSTF(24,0)

The TEXT Command The TEXT Command

The TEXT statement is used to assign a symbol to a string of characters.

Symbol = TEXT / string, string1, string2, … stringn

Search & Replace: the MODIFY option allows to perform a search/replace on a string :

newstr = TEXT / MODIFY, oldstr, searchstr, replacestr, nbtimes

Remove blanks: the OMIT option allows to remove blank from a string :

newstr = TEXT / OMIT, oldstr, option(where option =1 for trailing blanks, =2 for leading blanks, =3 for all blanks)

Note : Each time you want to print a text string coming from the CL file, do not forget to use : TXT=TEXT/CLW, TXT=TEXT/OMIT,TXT,1

POSTF FunctionsPOSTF Functions

POSTF allow access to the internal processing of the post-processor :

rslt = POSTF ( function_type,arg1, arg2, … argn)

rslt is a real or a string that reports the result of the operation.

Function_type is a two_digit number that represents the function type.

There are 27 POSTF functions.

PLABEL / OPTION, number , TO, value This command is used to access directly some of the

INTCOMs :

PLABEL / OPTION,1 ,TO,1 = POSTF ( 2,1,1831,1)WARNING : PLABEL is a CL command (and will be treated by GPOST as a CL command) and POSTF a function. It is

recommended to use POSTF(2 instead of PLABEL in a FIL macro

Examples :PLABEL / OPTION, 19, TO , 0 $$ Do not check travel limitsPLABEL / OPTION, 19, TO, 1 $$ Check travel limitsPLABEL / OPTION, 19, TO, 2 $$ Check travel limits and call

$$ _REPOS macro is neededPLABEL / OPTION, 65, TO, 2 $$ Special DPM for MILL/TURNPLABEL / OPTION, 88, TO, 1 $$ Axis registers non modalPLABEL / OPTION, 18, TO, 1 $$ remove redundant F code

The REPEAT Command is used to output an extra address and value automatically whenever a specific address is output.

REPEAT / register1, register2, value, [ON or OFF] register1 : register to force the output

register2 : register to output

value : value for the register

ON : register2 will be output for every occurrence of register1 until OFF is programmed.

REPEAT / register1, register2, ... Register_out, value, ALL

In this case any occurrence of either register1, register2, … registern will force the output of register_out with its value

Important : try to use REPEAT/OFF before a

You can assign a name to a group of statements and subsequently cause them to be executed each time you call the name.

The syntax is based on the APT macro call technique :

To disable a register you need to set the tape order of the register to 53

Tape order of register : INTCOM 1 to 26

XX=POSTF(2,1,intcom_val,53) to set the INTCOM to 53

To enable a register you need to reset its tape order to the initial value

Store the tape order of the register before disabling it : INTVAL = POSTF(1,1,intcom_val)

Restore the tape order : XX=POSTF(2,1,intcom_val, intval)

The SPWNF command spawns a sub-process :

SPWNF ( command, option)

command : text string containing the command line to be passed to the operating system

option : processing option, 0:process after the FINI (available only in Pro/E 2000i2 build 280 or better), 1:wait for process to return to GPOST before continuing and 2:continue GPOST processing without waiting.

Multi-axis milling machine with “orthogonal” axis : Main kinematics directly

available in the Questionnaire

Look at the machine with all the axis at “Zero”

Look at the axis of rotation, not the name of the register

Primary axis is the axis that GPOST is going to try to resolve first :

Table / Table configuration : Primary is the axis on which the part is going to be mounted

Head / Head configuration : Secondary is the axis on which the tool is going to be mounted

Note : there are some errors on the machine graphics in Optfile so do not rely on them for the kinematics !

A new option to control the automatic clamp/unclamp of the axes has been added. For each GOTO/ command, the required axes will be unclamped (M-code) before the move and clamped after.

INTCOM(4319) = 0, No clamp/unclamp needed – Default = 1, Auto axes clamp/unclamp required.

Set INTCOM(4320) = 0 to Unclamp each axis individually

Set INTCOM(4321-26) = to specify M-code for each xyzabc axis.

If set to zero then that axis will not be unclamped.
