Disk Re-manufacture

[Buzz239]

I tried to write a g code program to make a disk out 0.065" aluminum sheet. The disk is 2.75" in diameter with a .500" hole in the center. I've tried to get some quotes from several Jobbers and they want any where from $4 to $18 per disk. Lets face it we're talking about a lousy fender washer.

I tried to write some code, but I can't get it to line up. Any help would be apperciated.

Thanks Buzz

First off we need to know what kind of machine and control are you working with?

Why can't you get it to work? Why not post your code so we can look at it? What kind of alarms are you getting if any? What is it doing or not doing?

Generic g-code assuming a .250 end mill and X0 Y0 is the center of your washer and the top of your stock is Z0:

G0 X0 Y0
G0 Z.1

G0 X-.125
G1 Z -.065
G3 X-.125 I.125
G0 Z.1

G0 X-1.5
G1 Z -.065
G3 X-1.5 I1.5
G0 Z.1

Stevo,
I am running a Sable 2015 and k-Cam4 software. I think my main problem is, I don't understand all the ins and outs of the command G02 and G03. I seem to be relying on conversion programs that take a DXF files and convert them to Gcode. These tend to be very long compared to a G02 call. If you want I can post the Gcode but is quite lengthy.

I have several lists of Gcode calls with a 5 word description of what it does. I need to find a Gcode list with complete descriptions and examples.

Bob,
Thanks for the Gcode it helps out a lot and I can manipulate it to see what going on.

But always keep in mind that different machines have different idiosyncrasies or options set.

Often little stuff like is I and J incremental or absolute regardless of G90/G91
