ABSTRACT:
A numeric array of move command data Qi constituting a reference cam diagram F (.theta.) is stored in advance in a data table of a CMOS memory. Alternatively, a shift position of a cam corresponding to a rotational angle .theta. of the cam is stored in advance so that move command data can be generated by obtaining the shift position of the cam from the rotational angle of the cam based on the rotational angle value. In response to the input of a shift Ka in the lift direction, shift Kb in the pitch-circle direction, maximum lift Kc, and data number n as a criterion for extension or compression in the pitch-circle direction, the move command data can be corrected by automatic processing by means of a motion controller. Thus, final move command data Pk can be generated and outputted as position commands.
