Help With 4 axis MasterCam And FX10
can someone tell me why when we make a simple 4 axis program in mastercam with two 1 inch holes three inches apart at a 7.125 dree. angle. It looks good in mastercam but when we run it on the FX10 is turns out eggshaped.
thanks justin

Try to break both the upper and lower arcs in half so that all arcs are 180° segments... Somehow this gets MC to post the code correctly.

I've had the same problem with our Fanuc WEDM. It's not the machines or the post processor... Just a MC bug...

Does your machine use incramental programing in uv axis? example short line segments to create an arc? Mitsubishi do not use I's and J's to create arc. I have tried to break the program the circle into four sections and using by branch command, it looks not right on screen so I did not run it. thanks for your help.

Here is what the code would look like on my machine...

Is the trouble your having have to do with cutting a radius move at an angle and having it turn out conical on a mitsubishi fx10 wire machine?

[R Mak]

Let me get this you are cutting two 1" holes, 3" apart at 7.125 degrees correct. Are those two holes are in a plane that is tilted 7.125 degrees if so you are cutting on the hypotenuse the two holes will be Elliptical. If you view it perpendicular to the plane. Otherwise it will look round, viewed from the 7.125 angle
When it was cut.
