Pocket process brain formula.

[Kamran]

Hi All,

 

I am a research student, I want to know about the brain formula of pocket process, I mean the formula on which mastercam auto generates tool paths .....can any one help me ......

 

 

Best Regards

Hello;

 

The pocketing "Algorithm" in Mastercam would be considered intellectual property; so you will not see any formulas here.

If fact EULA's specifically state that the software is not to be reverse engineered, so trying to figure out how Mastercam does it, goes against that.

 

 

A google search finds a research paper that would be exactly what you are looking for.

ABSTRACT For die-cavity pocketing, contour-parallel machining is the most popular machining strategy. Two issues in generating contour-parallel tool paths for pocketing are: (1) a robust two-dimensional (2D)-curve offsetting algorithm; and (2) detecting and removing uncut regions. The 2D-curve offsetting solution has been widely studied, because it has so many potential applications. However, though the importance of the uncut problem in pocketing has long been recognized there have been few reported investigations on detecting and removing uncut regions. This paper presents a procedure for generating pocketing tool paths leaving no uncut regions. For the 2D-curve offsetting algorithm, we employ the PWID offset algorithm suggested by Choi and Park (Computer Aided Design, 31(12) (1999) 735) and expand the algorithm for offsetting areas having islands. Based on the expanded PWID offset algorithm, our solution to the uncut problem removes the uncut regions. Empirical tests show the usefulness of the proposed procedure for improving the productivity of pocket machining.

Ohhh I C ,

 

Well thanks for your feed back ALLAN,

 

Have a good day
