Cutting system, display system, processing apparatus, processing method, and processing program

A cutting system comprising:

• a cutting tool for performing a cutting process, the cutting tool including:
• a shank having a blade attaching portion, the blade attaching portion including a plurality blade fixing portions;
• a plurality of strain sensors attached to the shank, the plurality of strain sensors being for measuring strain of the shank;
• a memory sequentially storing measurement results obtained by the plurality of sensors during the cutting process by the cutting tool;
• and
• processing circuitry detecting an abnormality of at least one of a plurality of cutting blades attached to each of the plurality of blade fixing portions by repeatedly executing a process including the following (a)-(d) by accessing the memory during the cutting process by the cutting tool, wherein
• the processing circuitry is configured to:
• (a) generate, based on the measurement results obtained by each of the plurality of strain sensors at a plurality of measurement timings by accessing the memory, two-dimensional data for each of the measurement timings, the two-dimensional data regarding the load in multiple directions on a plane intersecting the rotation axis,
• (b) classify pieces of the generated two-dimensional data into any of a plurality of unit regions, a number of which is greater than or equal to a number of the plurality of cutting blades on the plane,
• (c) calculate an index value based on the two-dimensional data of each of the plurality of unit regions, including calculating a moving standard deviation of a distance from an origin of the two-dimensional data for each unit region, and
• (d) detect, based on the calculated the moving standard deviation for each unit region, an abnormality of at least one of the plurality of cutting blades, including:
• determining that an increase in the moving standard deviation is not caused by the abnormality of at least one of the plurality of cutting blades when all the moving standard deviations are increased,
• determining that an increase in the moving standard deviation is caused by the abnormality of at least one of the plurality of cutting blades when not all the moving standard deviations are increased.
