Abstract

A processing system includes a processing apparatus having functional units including a holding unit that holds a workpiece by a holding surface, a processing unit that processes the workpiece held by the holding unit, and a feed unit that moves the holding unit and the processing unit relatively. The processing system further includes a detecting unit that is provided for part or all of the functional units and detects any of vibration, current, voltage, load, speed, torque, pressure, temperature, flow rate, change in a taken image, and the thickness of the workpiece, and a data accumulating unit that accumulates information included in a signal output from the detecting unit as data.

First claim

What is claimed is:

1. A processing system comprising:
a processing apparatus having functional units including a holding unit that holds a workpiece by a holding surface, a processing unit that processes the workpiece held by the holding unit, and a feed unit that moves the holding unit and the processing unit relatively;
a detecting unit that is provided for part or all of the functional units and detects any of vibration, current, voltage, load, speed, torque, pressure, temperature, flow rate, change in a taken image, and thickness of the workpiece; and
a data accumulating unit that accumulates information included in a signal output from the detecting unit as accumulated data,
the processing apparatus further comprising,
a determining unit that determines states of the functional units on the basis of the accumulated data in the data accumulating unit, and
a normal data storing unit that stores information included in a signal output from the detecting unit when the functional units are normal based on a predetermined condition as normal data;
the determining unit comparing the accumulated data in the data accumulating unit and the normal data stored in the normal data storing unit and determining the states of the functional units,
wherein the processing apparatus is a cutting apparatus including, as the processing unit, a cutting unit in which a cutting blade that carries out cutting processing of the workpiece held by the holding unit is mounted,
the cutting apparatus includes a vibration detecting unit that detects vibration of the cutting blade as the detecting unit,
information on vibration when cutting processing of the workpiece is carried out by the cutting blade is accumulated in the data accumulating unit as the accumulated data,
information on vibration when cutting processing of the workpiece is carried out by a proper cutting blade corresponding to the workpiece is stored in the normal data storing unit as the normal data, and
the determining unit compares the accumulated data in the data accumulating unit and the normal data stored in the normal data storing unit and determines whether or not cutting processing of the workpiece is normally carried out.

2. The processing system according to claim 1 , wherein
the accumulated data in the data accumulating unit is used for any of quality control of the workpiece, management of the functional units, management of continuous operation, investigation of cause of a breakdown, and examination of an operation error.

3. The processing system according to claim 1 , further comprising:
a measuring unit that measures quality of the workpiece processed by the processing apparatus.

4. The processing system according to claim 1 , further comprising:
an XY-position detecting unit that detects a position of the holding unit or the processing unit in an XY-plane parallel to the holding surface;
the data accumulating unit associating information included in a signal output from the detecting unit with the position detected by the XY-position detecting unit and accumulating the information as the accumulated data.

5. The processing system according to claim 1 , further comprising:
a data output unit that outputs the accumulated data in the data accumulating unit.

6. The processing system according to claim 1 , wherein
the determining unit compares the accumulated data in the data accumulating unit and the normal data stored in the normal data storing unit and determines whether or not the cutting blade mounted in the cutting unit is proper.

7. The processing system according to claim 1 , wherein
the determining unit compares the accumulated data in the data accumulating unit and the normal data stored in the normal data storing unit and determines any of chipping, a degree of wear, and occurrence of clogging regarding the cutting blade mounted in the cutting unit.

8. The processing system according to claim 1 , further comprising:
a Z-position detecting unit that detects a position of the cutting unit in a Z-axis direction perpendicular to the holding surface;
the vibration detecting unit outputting a signal corresponding to vibration when the cutting blade mounted in the cutting unit moves in the Z-axis direction and gets contact with a circumferential part of the holding unit;
the data accumulating unit associating information on the vibration when the cutting blade gets contact with the circumferential part with the position in the Z-axis direction detected by the Z-position detecting unit and accumulating the information as contact data; and
the determining unit determining that a position in the Z-axis direction when the cutting blade gets contact with the circumferential part is a position of a cut-in origin of the cutting blade on the basis of the contact data.
