Hello,
Hopefully someone can help me with this problem, it's driving me mad! I have a recently purchased haas vf4, and when i'm machining radii the surface finish looks like a series of very small flats rather than a continuous radius. I am using a cam package to program the parts, and it makes no difference to the finish if i output the code in G02 and G03 moves or letting the program control the interpolation.
I have programmed other haas machines using the same cam package with the same settings and have not had this issue before. The steps are in line with each other if you machine in a number of z-level steps so i have ruled out the spindle and tool, i have checked the backlash compensation and it is ok, i can't help thinking there is a setting i am missing in the controller.
Straight line interpolation does not show the problem.
Can anyone help?
Thanks.
