Hi all,
I am trying to turn this shape. It's a pretty awkward boring job and what I struggle with is to get an accurate G-code
I am using Generic Fanuc Turning or Siemens the result is the same, the Z axis is correct the X axis is exactly the double. The cup radius is 25mm and I get lines such as this one:
N68 X45.816 Z-7.321
N69 X45.892 Z-6.253
N70 X45.947 Z-5.174
N71 X45.979 Z-4.086
N72 X45.983 Z-3.75
where 45.nnn is supposed to be the radius, therefore I would end up with a double diameter object... anybody experienced this?
Other strange thing that's happens is that it adds random circles at the bottom and at the edge of the cup.
They look like this on the code:
N22 G18 G3 X46.103 Z-2.392 CR=2.5
N23 G1 X46.125 Z-2.338
and like this in Mach3:
You can see those light blue scribbles at the bottom of the image and on the far left.
Yes I can edit the Gcode and delete them, but it would be great to fix this.
Does anybody have a clue on how to get around this?
Thanks,
Luca
