We created a cam by generating points in Excel.
The points are then used to create a XYZ curve.
This is extruded to an initial plank.
A circular cutter is drawn with the center on the curve.
A sweep of the cutter creates the cam.
We have a problem with the accuracy of this process.
A 40mm dia cutter cuts 19.9877. The interesting thing is it's not a consistent error.
I've simplified the process using a circle as a path and a circle as a blank.
The resaulting body shows a similar inconsistent error. The final body isn't round.
What should the process be?
Will we ever be able to machine a cam from a SW file?
