きなかつた。 Tool compensation in conventional numerical control (hereinafter referred to as NC) machine tools. Tool compensation such as tool diameter compensation is performed by measuring the difference from the reference value using a tool setter or other means with the tool attached to the tool holder, and using the difference as the tool compensation value by the NC machine tool operator manually or by using a tape. It was converted into information and input into the NC device. Therefore, in machines such as machining centers that store a large number of tools in a magazine and select the necessary tools accordingly, inputting the tool correction values to the NC device is extremely complicated, and even if sufficient care is taken, It is easy to make a mistake. Even if the tool correction value is converted into tape information, there is no difference from the manual method in that the operator associates the tape and the tool, which are two different things, and inputs it into the NC device. Obviously, the probability of making a mistake was high, and in any case, due to these unstable factors, a quick and accurate response could not be expected.

構成としたものである。 The present invention has been made to address the above-mentioned drawbacks, and is intended to automate and facilitate the input of tool correction values of tools into an NC device. In other words, the tool or tool holder itself has its own tool compensation value, and the compensation value for the amount of tool wear is input and stored as appropriate, and it is read out in correspondence with the tool, and the compensation value of the tool itself and the amount of tool wear are stored. The last tool correction value obtained by calculating the correction value of is automatically input to the NC device using a tool change completion signal and a tool number selection signal.

を自由に採用することができるのは勿論である。 Embodiments of the present invention will be described below based on the drawings. A machine tool to which this invention can be applied is, for example, a machine tool that automatically selects one specific tool from among a plurality of tools 2 of different shapes and dimensions that are held removably in a storage magazine 1 or held in a fixed position. In a machining center equipped with an automatic exchange arm 5 and an NC device, which is installed on the spindle 4 of the selected spindle head 3, the side of the tool holder 6 or the tool 2 has a deviation from the standard value measured by a tool setter or the like. That is, a label 7 on which letters or symbols are written or stamped is attached as tool correction information, which is the initial tool-specific error. The spindle head 3 is provided with a reading device 8, which reads the characters of the label 7 of the tool attached to the spindle and positioned at a fixed angle position according to a command. The reading device is a photoelectric type, for example, the label 7 has a non-reflective label base and the code and characters are written with light-reflecting paint, and the reading device is a photodetector with glass fibers aligned and the terminal end connected to a photodiode. This is a device that can recognize patterns by reading the light reflected from characters in the light emitted from the projector. If a magnetic type is used, a tape on which codes and characters are stored is attached as a label and read out by a magnetic reader. Of course, other devices capable of pattern recognition can be freely adopted.

容を修正するものである。 Next, a configuration for automatically reading tool correction information and inputting it to the NC device will be shown based on FIG. When the optical character reading device 8 receives a tool change completion signal a from another means (not shown), the optical character reading device 8 reads the tool correction information from the label 7 under the control of the reading control circuit 10, for example, Z123 (tool correction in the Z direction). The amount is read as a 3-digit decimal value 123) and inputted to A of the adder circuit 11 as the read tool correction value S1. This read tool correction value S1 is selected in conjunction with the output of the tool change completion signal a that is generated after one specific tool is automatically selected from multiple tools based on the tool number command of the tape information. This corresponds to the tool number of the tape information read from the tool. On the other hand, tool compensation setting dial 1 sets the compensation value when wear occurs due to inspection of the machined part as machining progresses.
2 is set with an appropriate correction value, and the memory write circuit 13
Tool correction values corresponding to a plurality of tool numbers are written in the set tool correction value memory 14 under the control of. The tool correction value selected by the tool number selection signal b based on the tape information issued from means not shown is read out from the set tool correction value memory 14 under the control of the memory read circuit 15, and the set tool correction value S 2 It is input to B of the adder circuit 11 as . In this adder circuit 11, the read tool correction value S 1
The set tool compensation value S 2 is added to the final tool compensation value S 0
The signal is sent to the function generation circuit 16 as a signal. The function generating circuit 16 receives command values C for each axis based on machining commands (not shown), performs tool correction using the final tool correction value S0 , and generates a function as the final command value.
and the position detection circuit 1 of the position detector 17 installed on the table or cross beam of the machining center.
A feed rate command f is outputted to the motor 20 via the servo amplifier 19 in accordance with the position information d obtained from 8. Further, the final tool correction value S 0 is sent to the display device 22 via the display control circuit 21 to notify the machine operator. The operator uses this display device 2
2 and corrects the contents of the set tool correction value memory 14 using the tool correction setting dial 12 as necessary.

There is no need to make correction settings. Furthermore, if only the set tool correction value is used without using the read tool correction value, the format is the same as the conventional tool correction input.

きる特長を有する。 As detailed above, the tool compensation amount specific to the tool and tool holder is stored as tool compensation information in the tool or tool holder itself, and the management of the tool compensation amount can be done in the same place as the tool management. Therefore, machine tool operators no longer need to pay attention to tool compensation during initial settings or when changing tools due to tool damage during machining. It has the advantage of avoiding the complexity of tool correction and preventing accidents such as damage to the machine body due to incorrect tool correction settings.
