Problems solved by technology

[0006] In the prior art, when the number of items of measurement data to be collected is large, the memory capacity for storing the measurement data increases, and the analysis time and processing time of the measurement data increase.
Also, since the sample cycle of the measurement data becomes longer, the accuracy of the measurement data tends to become coarser.
In addition, the abnormality detection process of the processing tool based on the position and distance of the processing tool tends to become cumbersome.

Embodiment Construction

[0017] (1. Structure of abnormality detection device for processing tools)

[0018] The processing tool abnormality detection device according to the embodiment of the present invention preliminarily sets, as a map, items of feature quantities described in detail later that need to be acquired for each type of processing tool, and collects and analyzes only pairs based on the set map. The measurement data of the feature quantity effective for each tool type is used to detect the abnormality of the processing tool.

[0019] Thereby, the number of items of measurement data to be collected can be reduced, an increase in memory capacity for storing measurement data can be suppressed, and analysis time and processing time of measurement data can be shortened. In addition, since the sample period of measurement data is shortened, the accuracy of measurement data can be improved.

[0020] like figure 1 As shown, the configuration of the abnormality detection device 1 of the process...

Abstract

An abnormality detection apparatus for working tools configured to be used in a machining process performed by a machine tool, the abnormality detection apparatus includes a storage portion which previously stores correlations between features of a plurality of operating portions relation to the machining process performed by the machine tool, and a tool condition of each of a plurality of workingtool types, and a tool condition determining portion which determines the tool condition of the working tools based on the correlations.

Description

technical field [0001] The present invention relates to an abnormality detection device of a processing tool. Background technique [0002] Conventionally, with regard to processing tools, the presence or absence of abnormality has been detected by collectively evaluating the number of workpieces to be processed and the processing time. However, a device capable of detecting abnormalities for each type of processing tool is desired. For example, the following devices are known: collect a plurality of measurement data related to processing tools from machine tools, and detect abnormalities of processing tools based on the collected measurement data; measure the position of processing tools in machine tools, and detect A device for abnormality of the processing tool; and a device for measuring the distance of the processing tool in the machine tool and detecting the abnormality of the processing tool based on the measured distance.
