Making a tooling plate - process help for machining
« on: January 31, 2014, 08:18:56 PM »
Hello,

I'm ordering a piece of MIC-6 to make a tooling plate for my Sherline 2000 mill. I have the A2Z CNC X & Y upgrades so the dimensions will be 1/2 X 6 X 17.  I'd like verify may process or hopefully get some input.

1) Square and secure the plate spaced off the table. The spacing is so the drilling op will not go into the table.

2) Drill the clearance hole for the hold down crews.

3) Mill pockets for hold down screws so the heads sit below the surface.

**** At this point I have some options ****

4A) Drill the tap holes for plate.

5A) Engrave an alignment grid

6A)  Square the edges of the plate.

*******************

4B) Stop, re-secure the plate to the mill table using the new mounting holes. I would still have it spaced off the table to protect it as before.

5B) Drill operation for the tap holes.

6B) Engrave an alignment grid

7B) Square the edges.

I like the B option better.  I think the tap hole drilling and engraving will be done more accurately.

Thanks,
Craig
