a joint could be a pivot or fulcrum. the machine control regards the mechanical instances of disjointedness as points of relative displacement, whether cartesian or polar or other.
the displacements along an axis with respect to another axis seems like it might as well be thought of in terms of the coupling between the two axes. --- On Wed, 4/11/12, Peter Blodow <[email protected]> wrote: > From: Peter Blodow <[email protected]> > Subject: Re: [Emc-users] German-language documentation, was: Downloading > Release 2.5 > To: "Enhanced Machine Controller (EMC)" <[email protected]> > Date: Wednesday, April 11, 2012, 1:48 AM > Thank you all for your thoughts about > the movement modes.
