Title: O-Ring grove with a side cutter?
Post by: ffulmer on May 10, 2011, 03:23:11 PM

Does anyone know how I could use the conversational programing to cut an O-ring grove around a stand up vertical post using a woodruff key cutter. I tried the thread milling with a zero lead but that didn't seem to work.

I don't know of any outside groove wizard BUT the Gcode is fairly easy to work out.

Sample Code for cutting a groove outside on a boss



F100
G0X0Y0Z1.000      (center over the boss)
G1 X2.4                   (Move out to a clear position Boss Radius + tool radius + clearance)
Z-.5                          (lowerZ to cut height)
G3 X1.4  Y0 R.5      (Move in to depth of cut for oring groove using arc leadin)
G2 X-1.4 Y0 R1.4    ( cut a circle in two parts)
      X1.4 Y0 R1.4
G3 X2.4 Y0 R.5      (Move back out to a clearance position using arc leadout)
G0 Z1.000                      ( Raise Z to a safe height)
X0 Y0                        (Move back to boss center)
M30

Just a thought (;-)TP

Thanks this will work. I only need to plug in the numbers.
