NUMERICALLY CONTROLLED APPARATUS AND NUMERICAL CONTROL METHOD.

摘要

A numerically controlled apparatus adapted to be moved in parallel with or perpendicularly to a designated shape for the purpose of producing a simple prototype easily by using a multipurpose machine tool. A graphic storage means (1) is adapted to display guidance information on a display unit (16) through a graphic control circuit (15), and store linear and arcuate designated shapes inputted thereinto interactively through an operation of a keyboard (17) by an operator. When an interpolation means (2) has detected a pulse signal HP outputted from a manual pulse generator (41), it reads a change-over signal H/V which is outputted from a change-over means, and which commands either a parallel motion or a perpendicular motion. The interpolation means (2) then outputs an interpolation pulse CP corresponding to the pulse signal HP and cange-over signal H/V, in accordance with the designated shape stored in the graphic storage means (1), and sends this pulse CP to an axis control circuit (18).
