Hi,

Have you made any parts from this NC code?

.010" wide sound very thin for a parting/grooving tool for this job, is it not .100"

If it is .100" then this is the code :-

G00 X0 Z0
G03 X.875 Z-.4375 R.4375 F1.
G01 Z-.5375
G03 X.250 Z-.9568 R.4375
G01 Z-1.
G00 X1.
M30

If you set the offset to the front edge of the tool then use this bit of code :-

G00 X0 Z0
G03 X.875 Z-.4375 R.4375 F1.
G01 Z-.4475
G03 X.250 Z-.8668 R.4375
G01 Z-1.
G00 X1.
M30

This will make the ball correct using the back edge of the tool on the back of the ball.

You can't do it like that, you can only do it in 2 moves, like this :-

G00 X0 Z0
G03 X.875 Z-.4375 R.4375 F1.
G03 X.250 Z-.8568 R.4375
G01 Z-1.
G00 X1.
M30

The problem you will have is getting the tool down the back of the ball.

Oops working to 4 places not 2

You can not have a radius bigger than half the diameter of the part with a Z move that is past the center of the rad.

if you want a .250 dia ball end on your bar you would enter :-

g20 g40 g90
g00 x0 z0
g03 x.250 z-.125 r.125
g01 z-.500
x1.
m30

Has the last line of the macro got a carriage return on it?

Will you post the macro and let me have a try here.

Have you got the macro saved in the correct directory.

If you are using a profile it must be in the profile's macro directory.  If not then in Mach3mill or Mach3turn's directory.
