Processing system, measuring probe, shape measuring device, and program

A shape measurement system comprising:

• a measuring unit attachable to a machine tool and generating measurement information for calculating a shape of a processing object of the machine tool;
• an acquisition unit which acquires position information generated by the machine tool and a generation time signal indicating a time at which the position information was generated as information related to a position of the measuring unit at a time of measuring the processing object by the measuring unit;
• an estimation unit which estimates the time at which the position information was generated based on a time at which the acquisition unit acquired the generation time signal and by estimating a jitter of the time at which the generation time signal was output by the machine tool;
• and
• a shape calculation unit which calculates a shape of the processing object based on the measurement information, the position information, and the time estimated by the estimation unit.

A shape measuring probe attachable to a machine tool, the shape measuring probe comprising:

• an imaging unit which generates measurement information of a processing object by imaging the processing object of the machine tool;
• an acquisition unit which acquires a generation time signal indicating a time at which position information generated by the machine tool is generated as information related to a position of the shape measuring probe at a time of measuring the processing object;
• an estimation unit which estimates the time at which the position information was generated based on a time at which the acquisition unit acquired the generation time signal and by estimating a jitter of the time at which the generation time signal was output by the machine tool;
• and
• an output unit which outputs the measurement information and information related to the time estimated by the estimation unit to a shape calculation device which calculates a shape of the processing object based on the measurement information, the position information, and the time estimated by the estimation unit.

A non-transitory computer-readable recording medium on which is recorded a program that is executable by a computer to cause the computer to execute:

• acquiring measurement information for calculating a shape of a processing object of a machine tool generated by a measuring unit attachable to the machine tool;
• acquiring position information generated by the machine tool as information related to a position of the measuring unit at a time of measuring the processing object by the measuring unit;
• acquiring a generation time signal generated by the machine tool as a signal indicating a time at which the position information was generated;
• estimating the time at which the acquired position information was generated by the machine tool based on a time at which the generation time signal was acquired and by estimating a jitter of the time at which the generation time signal was output by the machine tool;
• and
• calculating a shape of the processing object based on the measurement information, the acquired position information, and the estimated time.
