Crank 1 rotates about fixed axis A and is connected by turning pair B to slider 5 which moves along slot a-a of work table 2. When crank 1 rotates about axis A, table 2 reciprocates along guides d-d. Disk 3, mounted on table 2, is turned by an independent drive about axis C of the table. Crank 1 is periodically rotated and held stationary as required. This enables milling cutter 4, clamped in a fixed position, to mill a slot of profile b in disk 3. The obtained face cam enables simple harmonic motion to be produced with dwells at certain given parts of the profile corresponding to angles α and β.
