Prismatic Milling Hands-On Seminar Topics The seminar will be held at the Sequoia Etcetera training center located at 1200 E Copeland Rd, Suite 406, Arlington, TX 76011 on August 17, 2005 with four time slots available.
Thanx for all the replies. Someone requested a summary so here it is. They're all pretty much the same though.
Definition #1 (My favorite):
It is a buzzword (created by someone apparently unfamiliar with the shape of a prism) applied to milling simple parts with only vertical and horizontal surfaces.
I always thought it to be flat or normal surface machining... Face milling, profiling, pocketing and the like. Drilling, counterboring, boring and tapping would be included. Multi-side machining (as in tilting rotary table indexing) would be included provided it is positioning only, not interpolated. Essentially anything that does not involve 4 or more axis interpolation... No fancy surfacing like in die work or impeller/turbine blade machining.
Any form of milling where the tool axis remains stationary during the cut. This is not the same as 2 1/2D machining, which adds an additional restriction that the cutting plane be perpendicular to the axis of the tool.
Note that prismatic and 2 1/2D machining are also applicable to machines with rotary tables and/or heads. In this case, the rotary axes are oriented during RAPID (G00) motions, and stay stationary during cutting (G01) motions.
