Large chamfers

[Slixmix]

Well, not that large, just larger than the tool. We have a part that has some 1/2 X 45 deg. chamfers and we are using a 3/4 dia. chamfer tool to put them on. Any suggestions on what type of path to run. We have to step the cuts down obviously because the tool is too small to do it in one cut. Using v9sp1 level 3 w/ solids.

N FRANCO,

Look at the file I threw up on the FTP under MC9 directory called Chamfer_cuts.mc9

This is a simple down and dirty way of making large chamfers, you could also do it with the taper option under depth cuts.

I've done this one myself. As long as it is a 45 degree chamfer this works. Use a 2D swept toolpath with whatever stepover you want. Define the tool correctly especially the flat at the tip. Take the cutter diameter - dead spot take this number and multiply it by .352. Take the product and punch it in as negative stock to leave. I don't know how the math works out on this but it does. I'm sure someone can explain it.

 

good luck
