• Turns knob to adjust vernier gauges and obtain specified spacing of die mounts.
• Places die-racks in mounts and clamps racks in position.
• Places spline blank between machine centers and positions machine tailstock to accommodate length of workpiece.
• Starts and cycles machine to verify operation specified.
• Inspects trial run splines for conformance to specifications, using micrometer and gauges.
