  1. It's been there since 2018 , I actually asked for it in 2017 , but nobody ever informed me that this was acted upon. There has been talk of formalizing the feedback process ... I just love finding these little undocumented improvements . Gracjan

  2. Tabs Are the HOT SET UP on a lot of parts that become easy when you dont have to worry about holding them . Instant Tooling built into the material .!

  4. I would run a larger block of material, and face the top nice and flat, and contour an accurate profile with a Rough, Semi-Finish, and Finish Cut (with Cutter Comp). I would try really hard to hold the overall length and width to +-.0005. In Mastercam, I would use Transform > Rectangular (toolpath) to make multiple copies of the same part. Depending on length and width of the material, you may be able to get just "1 row", but do 4-6 parts, or even "multiple rows", where you are getting 18, 20, 24, or even 30 parts at a time. I would machine all of the "internal" pocket features, and machine around the "circular bosses", but I would not "profile" the outside of the part, lower than the "top of the flange" on Side 1. When you "flip the part over" for side 2, I would set the Work Offset to the "center of the block" and "top of the parallels", which are features I "cut" in Side 1. For finishing on side 2, I would profile those "bosses", and face the tops of all the part surfaces. To finish the part, I would profile (maybe Ramp), leaving a .01-.02 "web" of material holding the profile of the part, I would then take a smaller cutter, and make "Tab Cuts", which would leave just a few "Tabs" that are holding the part in place, with all the other features being finished. When OP2 is finished, you simply use a hobby (X-acto knife) to trim the parts out. The main benefit you get with this, is you don't you to build a fixture, and you don't have to spend any time transferring parts from OP1 to OP2. One of the things I dislike most is making Fixtures, when you don't need to. Use the Material itself, as the "fixture". In Aerospace, we call it "Window Framing". Use the "material" itself as the "fixture". The only time this doesn't work well, is with Cast or Forged parts, or "large" parts, where the extra material is expensive. For smaller Delrin parts, the amount of material you are throwing away is "dollars". Sounds like money well spent, in my opinion.

  5. Fixture all the way. Op 1 vise. Drill holes in the middle skim top. Op 2 down on fixture hold with screws through holes. Drill corner holes, mill outside contour steps and posts. Add screws through posts cut center out . Done 2 ops.

  6. sometimes bumping your step over up or down a tenth or so will fix this

  7. The "find overlap" c-hook is also very handy for overlapping geometry.

  8. There is a pdf document, available from you reseller, called 2018-MP_documentation. If you have trouble getting it, pm me. Also Colin offers post processing classes that, I can attest, are super informative.
