Abstract
Provided is a method for maintaining cutting quality in which a work surface can be reliably maintained at a predetermined hardness or less regardless of a disturbance during cutting. The method includes a data-acquiring step of acquiring, as a target cutting resistance, the cutting resistance of a machining tool (7) during cutting performed such that the hardness of a surface layer is lower than a predetermined hardness by adjusting machining conditions; and a cutting step of performing cutting while detecting the cutting resistance of the machining tool (7) during cutting and performing control such that the detected cutting resistance is lower than the target cutting resistance.
Claims8
A method for maintaining cutting quality, comprising:
- a data-acquiring step of acquiring, as a target cutting resistance in advance, the cutting resistance of a tool during cutting performed such that the hardness of a surface layer is lower than a predetermined hardness by adjusting machining conditions;
- and
- a cutting step of performing cutting while detecting the cutting resistance of the tool during cutting and performing control such that the detected cutting resistance is lower than the target cutting resistance.
An apparatus for maintaining cutting quality comprising:
- a data-acquiring unit that acquires, as a target cutting resistance in advance, the cutting resistance of a tool during cutting performed such that the hardness of a surface layer is lower than a predetermined hardness by adjusting machining conditions;
- a detecting unit that detects the cutting resistance of the tool during cutting;
- and
- a control unit that performs control such that the cutting resistance detected by the detecting unit is lower than the target cutting resistance acquired by the data-acquiring unit.
