Interesting Finish Texture
« on: November 24, 2021, 00:05:21 am »
I've been wanting to do this for a while.  I've done several simulations, but I finally had a chance to make some molds using it a few weeks ago.  The "arms" are a simple flat surface, but the "body" has a 3D contour.   

1.  I used the outline to create a single depth pocket using JK's Trochoidal milling method. 
2.  CamBam didn't seem to want to convert it directly to geometry so I created an NC file, and the used that to create an NC MOP. 
3.  The NC MOP was easily used to create geometry into an empty layer. 
4.  Then I exploded the geometry and used the select by type plugin to delete all the lines. 
5.  I mapped all the lines to a surface in a new new empty layer. 
6.  Finally I created an engrave MOP to cut the lines onto the surface.  Or rather I used them to cut the finish pass to the surface after leaving some roughing clearance in the preceeding roughing operation. 

The mold itself is really nothing special.  Its just a finish texture I have been wanting to do for a while.

If I have the time I'll be glad to show you a little in my shop.

Thank you guys. That is a commercial mold that I put up on my website, but what I was doing here was sharing a method of getting an interesting finished set of tool marks on a surface. Many years ago when I was told lazy cam was actually a cam program and not a method of defrauding people out of $75 I was able to make some limited parts with it and one of the things that lazy cam did was a spiral finish pattern. One of the first parts I ever made that I gave to somebody was a little aluminum heart box that I made for my wife and I finished it with a spiral pattern similar to that. It was flat, but at least initially until it oxidized it had a nice spiral pattern that came out from the center.
