Precision turning in metal and plastic. Pick a job, hit every dimension on the drawing.
How to play.Arrow keys turn the handwheels: ← → move the carriage (Z), ↑ ↓ the cross slide (X, read as diameter).
A tap moves one step, holding keeps it moving. 1 2 3 pick the step: 1.00 is rapid and must never touch the work,
0.10 is the cutting feed, 0.02 is for creeping up on a size. Q W E change tool.
Each material only takes so heavy a cut, so rough in passes. Every dimension on the inspection sheet has a tolerance:
green is in, red is scrap, and metal does not go back on.
Parting off ends the job. Best on a desktop with a keyboard.
The usual order.Face the end (turning tool at Z 0.00, feed in to Ø 0). Turn each diameter from the right end to its shoulder, biggest first,
and finish with a light cut. Groove: Z reads the blade's left edge, and it is 3.00 wide. Chamfer C on a corner: tip j to the right of the corner,
plunge to Ø − 2 × (C + j). Part off with the groove tool at Z −(length + 3.00).
