Workholding is the generic term for any device used to firmly hold your workpiece while machining it. Closely related terms are "jigs" and "fixtures.". A fixture holds your workpiece while it is being cut. A jig holds the workpiece and also guides the cutter. Given CNC, there's little need for jigs as the g-code guides the cutter, so

Should cost maybe $4000 to start drilling balls, less if you buy used.

Typically this ratio falls within the range of 20-40:1 (Figure 2). Example: Feed material at 50 microns. 0.05 mm x 20 = 1.0 mm bead. 0.05 mm x 40 = 2.0 mm bead.
