Newbee here with a question about tool offsets.
« on: February 25, 2008, 09:22:11 PM »
Trying to develop the g-code to do the gear teeth shown in the details attached. 

Problem is when I set the tool to a 1/16 (.0625 dia.) end mill and the connection tolerance to .001 (or any other value), LazyCam refuses to cut the area between the teeth; it wants to skim over the individual tooth tops.  In the cad file I’ve measured the distance between the teeth to be .114; that should be plenty of room for the cutter to offset between two teeth.

Interesting thing is if I ask it to offset it on the inside instead of the outside it has no problem creating the chain.
What am I missing here?

Good Morning Chip,
Attached is the DXF file for the gear, hope this helps in clearing up whatever it is I'm not getting.
Thanks for the help.

Hi, Tadd

I didn't pay attention to your second pic, LazyCam sometimes gets the in-outs backwards, Using LC 3.00.2 hear and in-outs are correct.

As long as the path is proper it should post it that way.

Thanks, Chip
