の間を利用して、刃先の状態を直接測定することができ
る。In a milling cutter or the like that performs interrupted cutting, the tool has a non-cutting time of at least half of one rotation period, so the state of the cutting edge can be directly measured using this time.
本発明は、この非切削時間の間に、回転中の工具の刃先
に光を当て、その反射光量を検出して工具の刃先の状態
を測定する方法を提供するものである。The present invention provides a method for measuring the condition of the cutting edge of the tool by shining light onto the cutting edge of the rotating tool during this non-cutting time and detecting the amount of reflected light.

れる。To explain the present invention in more detail with reference to the drawings, the first
As shown in Figures a and b, when cutting a workpiece W with an intermittent cutting tool T such as a milling cutter, the cutting edge 2 of the intermittent cutting tool T is in a non-cutting state during the intermittent actual cutting time. A detection head 1 for detecting tool wear and the like is installed so as to face the cutting edge of the rotating intermittent cutting tool T at a position where it is in a non-cutting state.

工具逃げ面の摩耗部２ａに当てる投光部と、その光線が
摩耗部２ａで反射する方向に設置されていて、反射光を
レンズ７で集光した後フォトトランジスタ８で受光する
受光部とによって構成されている。The detection head 1 includes a light emitting part that converts light emitted from a light source 3 into parallel light beams using a lens 4.5, transforms it into a band shape through a slit 6, and applies it to a worn part 2a of the flank of the tool, and a light emitting part that directs the light beam to a worn part 2a of the tool flank. It is installed in the direction of reflection, and consists of a light receiving section that collects the reflected light with a lens 7 and then receives the light with a phototransistor 8.
受光部のフォトトランジスタ８の出力は増幅器９を通し
てディジタル電圧計、シンクロスコープ等の表示装置１
０に表示させる。The output of the phototransistor 8 in the light receiving section is transmitted through an amplifier 9 to a display device 1 such as a digital voltmeter or synchroscope.
Display it at 0.

からの反射光の光量と摩耗幅の関係を求めた実験の結果
を示すものである。FIG. 2 shows how the light from the light source 3 described above is applied to the worn part 2a of the tool.
This shows the results of an experiment in which the relationship between the amount of reflected light from the worn part and the width of the wear was determined by reflecting the reflected light at the phototransistor 8 and detecting its output with a digital voltmeter.
同図かられかるように、上述した摩耗部からの反射光量
の検出によって精度のよい逃げ面摩耗幅の測定を行うこ
とができる。As can be seen from the figure, the flank wear width can be measured with high precision by detecting the amount of reflected light from the wear portion described above.

低くなって２つのピークを有する波形が得られることに
なる。Furthermore, when a synchroscope is used as the display device 10 to display the output of the light receiving section, when the above-mentioned flank wear occurs, a waveform as shown in FIG. 3a is obtained, but when the tool chips, the same waveform is obtained. As shown in the figure, the width increases and the level decreases depending on the degree of chipping, resulting in a waveform having two peaks.
したがって、これにより工具がチッピングしたか否かを
検出することもできる。Therefore, it is also possible to detect whether the tool has chipped or not.

簡単でモデルが不要であるなどの特長がある。As is clear from the detailed description above, according to the method of the present invention, tool wear and chipping can be detected and measured in-process using the non-cutting time of one tool rotation period, and in particular, If chipping occurs, it can be detected immediately, so the negative effect on the cutting surface can be minimized, and the equipment for measuring it is extremely simple and does not require a model. .
