Hi guys,
Would appreciate your help with something as I haven't been machining very long, so my experience if not as great as most of you on here.
I have completed a job previously (a batch of parts) have a proven program on a VF4 Haas that uses 4Axis. I have been asked to leave on 10 thou / 0.25mm to each side of this part (so part will sit higher on the fixture plate) to allow for skimming / any errors. The part is therefore sitting 0.25mm higher on the plate, and the very top face of the part is therefore 0.5mm higher than intended. The program has essentially been written long hand as no CAD/CAM.
How do you think it's best to adjust the heights? I cannot simply put a 0.25mm tool offset in because some tools are used in multiple A axis angles.
Any ideas for resolving this would be greatly appreciated.
TIA.
Dan
