It can be controlled by inputting it, but if you input the needle-buchi characteristics of the needle-buchi tool, the machine program will become extremely complicated, and for some reason you will have to continue machining the workpiece manually. Work efficiency will be significantly reduced if an unexpected situation occurs.

ラムが自動的に補正される。As shown in Figures 1 and 2, multiple measurement tools (Tt) (T2) attached to the main spindle (1) of a numerically controlled machine tool, for example, a machining center (M), each have different A resistor (2) and a differential transformer having a function of measuring workpiece dimensions and having different specific resistance values (Rs) (R2) and a differential transformer are used to determine each measurement function as a change in physical quantity. (5). On the other hand, a measurement correction device (3) having an amplifier (4) is connected to the spindle head of the machining center (M). Therefore,
The measurement tool (
When the resistor 13 (2) having the specific resistance value (Rn) is attached, the resistor 13 (2) having the specific resistance value (Rn) is electrically connected to the main body side of the measurement correction device (3). In this way, the specific resistance value (Rn) of the resistor (2) is measured on the measurement correction device (-3) side, and this measurement result is shown in FIG.
machining center (M) as a characteristic discrimination signal of
transmitted to a data file on a computer connected to the computer. The cutting conditions of the workpiece at the machining center (M) are calculated based on the verification results in the data file,
The cutting conditions are used as a correction signal in the workpiece processing nibogram (P
) is input. In this way, a correction signal for the cutting conditions of the workpiece, for example, the feed rate of the workpiece or cutting tool, is sent to the machining center, and machining of the workpiece using the corrected cutting conditions is started. In other words, even if multiple measurement tools (Tn) each have different measurement characteristics, the measurement characteristics can be accurately determined as voltage changes due to differences in specific resistance values (Rn), and these measurement tools Using the characteristic determination results of the tool (Tn), the workpiece's uniform program is automatically corrected.

於いてその信頼性が著しく向上する。C1. Effects of the Invention As can be understood from the above explanation, the method of the present invention allows the characteristics of a measuring tool attached to the main shaft of a numerically controlled machine tool to be calculated from the specific resistance of the resistor built into the measuring tool. It can be accurately determined by using changes. Therefore, the characteristics of the measurement tool currently mounted on the spindle can be determined on the measurement adjustment device side even without a determination signal from the numerically controlled machine tool side. In this way, there is no need to incorporate a measuring tool discrimination function into the workpiece cutting program as in the past, and the operability and workability of the measuring tool during manual operation are greatly improved. Furthermore, if the measurement tool discrimination capability is input into the workpiece machine program, it is possible to compare the measurement tool information sent from the machine program with the measurement tool actually attached to the spindle. Therefore, the reliability in determining the characteristics of measurement tools is significantly improved.
