Refer to the “Stock Surface Identification” sheet on the angle plate print. Side #1 1) Remove burrs from workpiece and clean. Clean vise. 2) Set workpiece in vise on two parallels with large surface facing up. Select the shortest parallels possible which provide sufficient clearance for the surface to be machined and ensure maximum clamping surface area. 3) Tighten workpiece in vise. Do not clamp on bandsaw cut surfaces. 4) Mount face mill in machine spindle. “Touch off” cutter on top of workpiece with quill. Use gentle pressure to avoid chipping cutting edges. Tighten quill clamp. Set dial on knee (Z-axis) to zero. Lower knee one full revolution with crank to move workpiece away from cutting tool. 5) Clear workpiece to side of cutting tool and raise knee back to “touch off” position. Raise workpiece .020”-.030” past “touch off” position to set depth of cut. 6) Set correct RPM. On milling machines with variable speed drives, do this with spindle on. On milling machines with belt drives, do this with spindle off. 7) Turn spindle on. Check for correct direction of cutting tool rotation. Mill off top of workpiece using power feed on X-axis. Take multiple passes if necessary to machine entire surface. Make adjustments with Y-axis. 8) Turn machine off. Remove and clean workpiece. Deburr newly-formed edges. Side #2 1) Clean vise and parallels. 2) Place deburred workpiece on two parallels with Side #1 against fixed jaw of vise. 3) This time, place a soft metal pin (copper, brass or aluminum) between the workpiece and the moveable vise jaw horizontally. Tighten workpiece in vise. 4) Repeat all procedures from Side #1. 5) Turn machine off. Remove and clean workpiece. Deburr newly-formed edges. Side #3 1) Clean vise and parallels as before. 1) Place deburred workpiece in vise with Side #1 against fixed jaw of vise and Side #2 on one parallel. Use the pin again between the workpiece and the moveable vise jaw. 2) Partially tighten vise. With soft-faced, or dead-blow, hammer, tap workpiece down until both sides make positive contact on one parallel and tighten some more. Repeat and finish tightening. 2) Repeat all procedures from Side #2. 3) Measure the workpiece with a dial caliper. Continue to machine to rough size for width of part (2.430”). Make adjustments with knee crank (Z-axis). Do not take cuts over .030” when workpiece is clamped in vise against pin. 4) Turn machine off. Remove and clean workpiece. Deburr newly-formed edges. Side #4 3) Clean vise and parallels as before. 4) Place deburred workpiece in vise with Side #1 on two parallels and Sides #2 and #3 clamped between jaws. The pin is no longer necessary. Tighten vise as before and tap down workpiece until both sides make positive contact on both parallels.
