Description
前記ヘッドの移動速度の適正値は一定ではなく、工具の種類（大きさ）、被加工物の材質や形状により大きく変わる為、前記移動速度を一定としたまま、この移動速度を適正値に維持する事は難しい。この為、前記工具を固定した回転軸に加わる荷重を測定する事により、前記移動速度を適正値に調節する事が、従来から知られている。即ち、工具により被加工物に切削等の加工を施す際には、加工抵抗により、この工具及びこの工具を固定した回転軸に荷重が加わる。この加工抵抗、延いてはこの回転軸に加わる荷重は、前記移動速度が速くなる程大きくなり、逆に、この移動速度が遅くなる程小さくなる。そこで、前記荷重が所定範囲に収まる様に、前記移動速度を調節すれば、この移動速度を適正範囲に収める事ができる。 The appropriate value of the moving speed of the head is not constant, but varies greatly depending on the type (size) of the tool and the material and shape of the workpiece. Therefore, the moving speed is kept constant while keeping the moving speed constant. It is difficult to do. For this reason, it is conventionally known to adjust the moving speed to an appropriate value by measuring the load applied to the rotating shaft to which the tool is fixed. That is, when a work such as cutting is performed on a workpiece with a tool, a load is applied to the tool and a rotating shaft to which the tool is fixed due to processing resistance. The machining resistance, and hence the load applied to the rotating shaft, increases as the moving speed increases, and conversely decreases as the moving speed decreases. Therefore, if the moving speed is adjusted so that the load falls within a predetermined range, the moving speed can be kept within an appropriate range.
この様な目的で、工作機械の主軸等の回転軸に加わる荷重を測定する為の装置として、特許文献１に記載された発明装置が従来から知られている。この特許文献１に記載された発明装置は、水晶圧電式の荷重センサを複数個、荷重の作用方向に対して直列に配置し、この荷重センサの測定信号に基づいて、切削工具を支持固定した回転軸（スピンドル）に加わる荷重（切削抵抗）を測定する様に構成している。この様な特許文献１に記載された発明装置の場合、高価な水晶圧電式の荷重センサを使用する為、荷重測定装置全体としてのコストが嵩む事が避けられない。 For this purpose, an invention apparatus described in Patent Document 1 has been conventionally known as an apparatus for measuring a load applied to a rotating shaft such as a main shaft of a machine tool. In the invention apparatus described in Patent Document 1, a plurality of quartz piezoelectric load sensors are arranged in series with respect to the direction of the load, and the cutting tool is supported and fixed based on the measurement signal of the load sensor. The load (cutting resistance) applied to the rotating shaft (spindle) is measured. In the case of the inventive device described in Patent Document 1, since an expensive quartz piezoelectric load sensor is used, it is inevitable that the cost of the entire load measuring device increases.
