I have recently purchased a Hurco kmb1 mill. I have used it a little using the hurco conversational programming but now I am trying to program it using bobcad 21.
I am trying to mill out the profile of a rocker arm for a pulling tractor. I tried using the post processor that was supplied by Bobcad and the machine won't even take the program because it has to have a % sign at the start of the program.
I have contacted the previous owner of the mill and he used to program it with bobcad v 20. He helped me a little but something is still not right.
I am milling the rocker in 4 passes each at .250 deep at an offset of .280 using a .500 cutter. This gives me a .030 finish pass.
My main problem is that the cutter will plunge to -.250 and start milling but on arcs it ramps up to 0 by the time it gets to the start of the next arc when I want it to stay at -.250 and cut all the way around the part. Also when I get to milling out the 1" hole in the center of the rocker, the mill stops and says "bad arc DB" . I don't know if the problem is in the way I draw the part or just the way post processor is producing the g-code? By the way, the simulation in bobcad seems to work just fine.
Any help would be appreciated.
Here is my program
If the previous owner used BCC to program this machine you can Copy his Post Processor into your BCC files and use it.
This might help you to produce good G-Code for your Mill.
