Provided is a tool wear monitoring device configured to input a plurality of pieces of image data captured with a microscope camera while changing an angle, and to monitor tool wear. The tool wear monitoring device includes a data analysis unit configured to analyze image data. The data analysis unit binarizes the plurality of pieces of image data captured while changing an angle, extracts data in which a worn region has a maximum area among the plurality of pieces of image data, and analyzes the amount of wear from the extracted data with the maximum area.

Tool wear monitoring device, tool wear monitoring system, and program

The present invention provides a technology for generating an NC program which can secure appropriate machining accuracy. Provided is a conversion computerwhich includes a CPUand generates an NC program for a turning process for a workpiece on a lathe, wherein the CPUis configured to generate an NC program such that displacements caused for a workpiece to be processed on a plurality of machining positions at a time of a turning process are calculated, on the basis of the displacements caused for the workpiece on the plurality of machining positions, a movement path of a tool to be used at the time of the turning process is decided, and the tool is moved through the decided movement path.

NC program generation system and NC program generation method

The present invention makes it possible to convert an NC program used for one processing into an NC program capable of securing appropriate processing accuracy in another processing machine. Provided is an NC program conversion process method by a conversion system which converts a conversion source NC program for executing a processing in a conversion source processing machine into a conversion destination NC program for executing a processing in a conversion destination processing machine, wherein an input of information relating to (1) stiffness of the conversion destination processing machine or (2) stiffness of the tool included in a conversion destination toolset is received, and on the basis of the received information relating to the stiffness, a conversion source NC programis converted into a conversion destination NC program

NC program conversion process method and processing treatment system

A side milling cutter for slot cutting is provided whose vibration can be damped even in cases where a vibration mode of the cutter generates plural nodes in a cutting part. A side milling cutter for slot cutting of the present invention includes a disc-shaped cutter and a plurality of cartridges as cutting edges provided at a predefined interval in a circumferential direction along an outer circumference of the disc-shaped cutter. The disc-shaped cutter cuts a predefined slot on a workpiece using the cartridges by circumferentially rotating. The disc-shaped cutter internally includes a plurality of vibration damping structures in the circumferential direction on a disk surface of the disc-shaped cutter.
