macro samples / explanations

[specprogrammer]

We just took delivery of a hurco VM1 graphite mill. It has a fixture on it with 12 positions for cutting electrodes. Its four rows in X three in Y. We usually cut three identical trodes. So I want to write a program that moves to the 1st position, calls the sub, moves back to the second position, calls the sub, moves back to the 3rd, calls the sub, then moves to the second row and calls the second sub program, and so on. I need to write a macro because the machine doesn't have enough work offsets (G54-G59). Its been about 12 years since I had any contact with a macro and it wasn't very much. Does anyone have a similar program? Or can anyone show me a sample program to get me started in the right direction? Heres what I'm using to get me through right now.

I'd love to replace those G52's with some variables. That way I could have several different variations of this program and a seperate place with all the locations.

not a hurco guy but is this what you are trying to do

 

G52 X#501 Y#502

 

#501=0

#502=4.

How about something like this? Haven't tested but use with caution!

 

%

#101=0 (X POSITION)

#102=0 (X COUNTER)

#103=4 (X SPACING)

#104=3 (X QTY)

 

#105=0 (Y POSITION)

#106=0 (Y COUNTER)

#107=4 (Y SPACING)

#108=4 (Y QTY)

 

G54

#106=0 (Y COUNTER SET)

N1 (RETURN FROM Y INCREMENT)

IF [#106 EQ #108] GOTO 20 (REACHED Y QTY - END LOOP)

#102=0 (X COUNTER SET)

N5 (RETURN FROM X INCREMENT)

IF [#102 EQ #104] GOTO 10 (REACHED X QTY - END LOOP)

G52X#101Y#105

M98P1000

#102=#102+1 (INCREMENT X COUNTER)

#101=#101+#103 (ADD X SPACING)

GOTO N5

N10 (END X LOOP)

#106=#106+1 (INCREMENT Y COUNTER)

#105=#105+#107 (ADD Y SPACING)

GOTO N1

N20 (END Y LOOP)

Did you try this out ...!!!

[Rick46]

not trying to hijack the thread but trying to understand.. what do the variables allow u to do versus the main program with the G52's on it? Im curious because im getting ready to go to a similiar setup and situation with electrodes my self..currently have six 3R blocks but are going to add 3 more for a total of 12 as I only have 6 work offsets I can see this main program u have working really well for what I would need in my situation.. just curious what the varaibles can do or would allow me to do in my programs.. thanks..

[Simtech]

The variables allow you to have the output to dynamically change according to there values.

 

You could also assign this macro with addresses and call it out like this:

M98 P9999 A0 B0 C4 D3 L0 M0 N4 P3

 

Each value assigned to an address could be used in the macro.

 

Hope this helps!

Call Hurco and ask for Gerry Traicoff... He is very good at helping / explain what would be needed
