Chip thinning and Mastercam

Recommended Posts

Hello Guys,

I'm machining a 1.25 wide slot 4.5 deep using a 1.0 high feed cutter.

The first part of cutting the slot is full diameter of the tool but on the way back the radial depth of cut is .25 so I use the chip thinning formula and my increased my feed.

 

The question I have is how do I get Mastercam to post that out, I don't want to manually go into the program and change the feed for every depth cut.

 

I played with the High feed settings in Mastercam but I'm not getting the desired results, but it could be that I'm not using correct settings.

 

Any ideas?

 

 

TIA,

Greg

In order to make "in-cut" feedrate changes, you'll either have to use the Toolpath Editor, or use the "Change-at-point" function in the chaining menu.

"2D High Feed" Toolpath, then there is no full-diameter pas

Colin can you explain the change at point function to me.

 

Henk, yes that is an option, thanks for pointing that out.

I did figure out the change at point function I just wanted a explanation from an expert.

Hi, GREG,

 

I think you should change contour mill to Peel Mill.

 

In the peel mill setting, you can increase the feed rate to a higher value, and set the step over value to about 7%(it depends on the material and tools)

 

i post a picture to explain what i mean

 

hope it will be helpful.
