General Mach Discussion / Will Mach3 let me pass the edge of a job past a fixed welding torch
« on: May 12, 2013, 05:33:08 PM »
Hi,
Complete newbe, first post.
I am trying to build a table that passes the outer edge of a rectangular flange with rounded corners past a MiG torch max size 1000x650mm
It's a bit like holding a paintbrush out in front of you to paint a stripe around the outside of a biscuit tin as it passes by.
I think I need X,Y and C rotation. The only way I can work out to do this is to have the job centered on a turntable that is driven X,Y.
I think I have worked out a tool path that would work but it looks like a capital "D" on it's back with a Parallel line inside the "D"
I could move X until I get to a corner then rotate the job around the center of the corner radius by rotating the table 90 deg and moving the center of the job in an opposite arc to the corner at the same time.
This all seems a bit messy, is there a better way of passing the edge of your job past a tool like a grindwheel for example.
Im finding this a bit tough for my intro into CNC, If only I could have started with a 3 axis mill.
