Suppose that the plate shown in Figure 26-B was to be profile milled around the periphery with a 1-in.-diameter end milling cutter. The dashed line is the cutter path. The programmer must calculate an offset path to allow for cutter diameter. Since the programmed points are followed by the cutter centerline and the profile is made at the tool's periphery, the programmer called for a ½-in. cutter offset. Working with computer assistance, the programmer would describe the part profile to be machined and specify the cutter .The computer would generate the cutter path. Complete the table below to specify the cutter path, starting with the origin at the zero reference point. Move the tool around the plate counterclockwise.
