Abstract

A processing apparatus with a movable processing tool, includes a deflection detecting device, a rotating position detecting sensor, an arithmetic unit, an output circuit, a fine adjustment device, and an XY table. The detecting device detects a plurality of deflection amounts of a processing reference surface of a to-be-processed work held by a work holding member mounted to a main shaft of an NC processing apparatus. The sensor detects a rotating position of the work. The unit calculates a correcting amount of the tool at a processing point of the work from a measured value of the sensor and plural measured values of the deflection amounts of the detecting device. The circuit outputs the correcting amount synchronously with the rotating position and processing point of the work. The adjustment device has the tool fixed thereto for finely moving the tool in a processing direction based on an output from the circuit. The fine adjustment device is secured to the XY table.

Dependent claims

A processing apparatus with a movable processing tool, which comprises:

a deflection detecting device for detecting a plurality of deflection amounts at points which are axially spaced on a processing reference surface of a to-be-processed work which is held by a work holding member mounted to a main shaft of an NC processing apparatus;
a rotating position detecting sensor for detecting a rotating position of the work;
an arithmetic unit for calculating a correcting amount of the processing tool at a processing point of the work from a measured value of the rotating position detecting sensor and a plurality of measured values of the deflection amounts of the deflection detecting device;
an output circuit for outputting the correcting amount synchronously with the rotating position and the processing point of the work;
a fine adjustment device having the processing tool fixed thereto for finely moving the processing tool in plural processing directions based on an output from the output circuit;
and
an XY table to which the fine adjustment device is secured.
