Hi guys,
I've been cutting some shafts today on my ST-20 and I've come across a bit of an anomaly I can't figure out - I'm hoping someone with a bit more experience may be able to shed some light for me!
Program goes as follows:
N100 G00 X34.6;
G01 G42 Z0. F0.12;
X34.8 Z-0.1;
Z-100.;
X35.8;
X36. Z-100.1;
Z-406. ,R0.600;
N200 G00 G40 X42;
Now for some reason on the Z-406 move it cuts a programmed 0.234 mm taper and this is displayed in the "distance to go" positions screen as it counts down to 0 when Z reaches -406. If you remove the G42 line entirely it cuts straight but the 0.1 chamfers are missed due to the tool nose radius.
At first I thought maybe a taper correction was programmed somewhere but I can't see an option for it on the tool offsets or in a settings search for taper. What's also puzzling is that this does not happen on the X34.8 mm diameter, only the X36.0 mm diameter.
Any help would be greatly appreciated!
