Newbe needs help with rest mill tool path

[Chuck Haigler]

Hi Guys

Hope someone can help me I am a new MC user using Ver 7 doing a 2D High Speed (2D Dynamic Rest Mill) I have a 2.5 dia hole I am milling it out to be a 2.515 square with .5 radius in the corners.

When I post out the tool path I get a whole bunch of XY moves on the return path it makes the program very large is there any way to suppress these XY moves and make the program smaller or there a reason for them that I am not seeing.

Thanks for the help

Take a look at the attached file here. Main thing is turn on arc filter. Also I put .010 stock to leave for roughing, set the total tol to .005, and make sure you adjust the slider towards arc/line tolerance. Then for restmill set stock to leave to 0, then total tolerance to .001 or so. However you don't have a finish pass with these two toolpaths, so it will need a contour to finish the walls.

 

 

Another way instead of rest is dynamic contour. It's nice because it has a finish pass with cutter comp rolled into the toolpaths. You have to make sure you set up the "contour wall" page with the appropriate numbers BASED on the previous toolpath. (kinda restmill-ish but you enter the data, also note that it's asking for radius values, yes even though everyone-and-their-mother defines tools by diameter).

Thanks Chris that is what I was looking for I had not got to the finish pass yet.

 

Thanks Again
