Steve; Does your machine have a Mazatrol control? We have about a dozen Mazak Mills and 3 lathes all with Mazatrol controls (M2,M32,M-plus,T-pus,T32,Fusion 640). If the control is Mazatrol, do you have the same problem programming in Maztrol conversational? These controls have 2 modes of operation, Mazatrol conversational, and standard G,M code. I have run into the same problem on occasion. The problem is in the control not the software that programs it (as long as SmartCAM is set to output 4 decimal places). We have run the same programs in other machines, without modification (that would be the G,M code programs) and they have run just fine. Mazak seems to have a tolerance situation when it comes to arcs. To work around it, most of the time we just have to change 1 coordinate (X,Y,I,orJ) by .0001, sometimes add sometimes subtract, it's basically a crap shoot, and this lets the program run just fine. It seems to me that the control is truncating the calculations. I say this because I've calculated the coordinates for some of the problems myself out to 10 decimal places and the numbers that we had to change to get a program to run were not rounded properly (the modified numbers, SmartCAM output them correctly).
Also, if your programming part boundary and offsetting your laser with G41,G42, try turning off the lookahead parameter in the control (if it has one). The control looks ahead in the program by a number of blocks (usually 5) and adjusts the program if needed to fit the offset of the cutter. I have never programmed a laser so my terminology is in the milling context. This has helped on occasion for us. Sorry I couldn't give you more foolproof solution, but this seems to be the nature of the beast. :) Cheers, Chuck Glawe Courtesy Corporation Mold & Tool Div.
