Programming Problems

Recently came into ownership of a slide cnc with a fagor 8025 control, and I'm having trouble using variables, and such.. here is what i need converted.

any takers? I've tried using different variables from V01-V-299 i believe the first 19 are used for set canned cycles... but still no advice.. its like the fagor doesnt even recognize the variables.

Yes, the 8025 can easily do it, you just have to convert it to the appropriate format that 8025 requires.

If you have the programming manual, you will see it uses certain F codes for mathematical functions. For example, F1 is addition.

N0 P1 = P2 F1 P3 (Adds P2 and P3 together and puts the value in P1)
N10 G01 X P1 F50 (Positions the X axes to the value in P1 at 50 ipm)

another example:

N0 P1 = K5.521 (Gives P1 the value of 5.521)(you must have that K before a numeric value)
N10 Z P1 (positions the Z axes to the value in P1

There are F codes for most mathematical functions including multiplication, division, cosine, Arc tangent, square root and others.

There are some parameters with predetermined fixed meanings as well, but all of this is covered in Chapter 13 of the 8025 T programming manual. If you do not have a Programming manual, let me know, and I will email you an electronic copy. Once you give it a quick read.... it'll be simple. I used to do some very complex parametric programming with the 8025 about 20 years ago.

I think once you know the basic format and commands, it will take you 5 minutes to convert your shown program over.

good luck !

hai,
i want to know about,how to use peck drilling cycle in sinumerik 840 c? for EX; DRILLING CYCLE WE USE R LIKE R02,R03,R10 ,so what are r used for peck drilling, please help ...


thanks ,
