shaving. like planing or scraping or chiseling, or sorta like broaching. ive made a few parts like that with internal square cube corners even on top of ball screws. takes forever, and the cutters are custom. thru cuts would be easier, like an incrementally stepping punch.
if overall footprint is not an issue, scale everything up and use an endmill. ..or a bandsaw. or a hyrdoabrasive jet or a laser. or a lamination process. or a 3d voxel type printer. --- On Sun, 5/13/12, andy pugh <[email protected]> wrote: > From: andy pugh <[email protected]> > Subject: Re: [Emc-users] Some advice needed > To: "Enhanced Machine Controller (EMC)" <[email protected]> > Date: Sunday, May 13, 2012, 4:38 AM > On 13 May 2012 12:04, charles green > <[email protected]> > wrote: > > wire electric discharge cutting? > > I was thinking that might be the easiest approach for low > volume. > > How many of these do you need to make?
