yes!
Hello
Can anybody tell me if it’s possible to mill an ellipse with a milling head on a Weingärtner Rotomill MPMC (turn-milling-machine) with Siemens 840D controller????
yes!
Here an example program.
ASCALE Y 2.0 ;scaling Y axis one factor 2, 1mm programmed traverse path are 2mm
N80 G0 X0 Y0 Z2 M107
;simply program a 30 circle
N10 G0 X0 Y0 Z2
N40 G1 Z-5
N45 G1 X-15 Y0
N50 G3 X15 Y0 CR=15
N55 G3 X-15 Y0 CR=15
N60 G1 X0 Z0
N65 G0 Z5
SCALE ;scaling deselection
creates an oval of 30mm in X and 60mm in Y
It’s actually quite simply, hope I was able to help you out!
Kind regards
Hugge
Yes that a way to do it when you mill in X and Y and the tool axis is Z.
Because it’s a Weingärtner Rotomill MPMC (turn-milling machine) I can imagine quite well that the ellipse is milled on the jacket and that the milling axis lies on the Z axis. But it’s not clear in the question. We will need more information: a sketch, setup situation and more details about the tool.
