I am testing a rotary axis (added to my 3 axis router), to which the part is to be mounted. The rotary axis is mounted on the X axis, which in turn is mounted on the Y axis. The Z axis is independent and carries the cutter. Following the advice in Jeff Epler's post quoted below, AXIS shows a tool path that reflects the effects of all 4 axes, but I think from the part's frame of reference, which makes it hard for me to follow the action.
Can AXIS be configured to show the tool path from the operator's frame of reference (i.e., the global coordinate system)? I would like to see the part rotate about A, and translate along X and Y, and the cutter move along Z. Does this make sense, or have I inhaled too much varnish tonight? > From: Jeff Epler <jep...@...> > Subject: Re: Axis question > Newsgroups: gmane.linux.distributions.emc.user > Date: 2009-04-19 19:32:59 GMT (13 weeks, 3 days, 2 hours and 53 > minutes ago) > Yes, this is one of the new features in emc 2.3.0.
