JPH05138474A - Tool management method using tool id by personal computer(pc) - Google Patents

Abstract

PURPOSE:To conduct tool control by correcting tool data in a work program of an M/C side, and transmitting, on the M/C side, information on a working tool and breakage and the like of a tool every time to a personal computer (PC) side by means of a control code to renew tool information stored in the PC. CONSTITUTION:Information on tools is beforehand stored in a personal computer (PC) and an ID element 7 of a tool 5. Information transmission between the PC 1 and an M/C 8 is performed by means of a control code 9 which is ordinarily used in general. When a desired tool 5 is fitted into a main spindle 10 based on a work program, reading of the ID element 7 in the tool 5 is conducted so that information related to that tool 5 stored in the PC 1 is called every time when the PC 1 is operated. Accordingly, information related to the tool 5 in the M/C 8 is renewed and predetermined work based on this renewed tool content is conducted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a tool using a tool ID by a PC which transmits tool information to or from the M / C side without using a complicated communication means (protocol). Regarding management method.

[0002]

2. Description of the Related Art A method of integrally mounting an ID element on each tool and writing various information about the tool in the ID element to manage the tool has been adopted in recent numerical control machine tools. In that case, in order to rewrite the tool information in the ID element or to read the tool information in the ID element, for example, a read / write head is provided in the main shaft and an ID controller or the like arranged outside the machine is used. A method of inputting to a CPU or the like is adopted. In that case, it is common to use a special protocol such as a half-duplex method as a communication means.

[0003]

In the tool management method using the communication method by the special protocol, there is a problem that the equipment cost increases and it is difficult to retrofit the existing machine easily. Occurs. Also, CP
The tool management using U can be applied to a relatively large-scale factory, but there is a problem that it is difficult to apply it to a small-scale place. In addition, a large number of tools are used even in a small place, and it is necessary to manage spare tools, and at the same time, grasp tool damage, changes in tool shape, service life, etc. Rewriting and memorizing is necessary for high precision processing and productivity improvement.

The present invention has been made in view of the above circumstances and has been devised in view of the above circumstances. It uses a relatively easily available PC and does not use a complicated communication method (protocol). It is an object of the present invention to provide a tool management method using a tool ID by a PC, which enables information transmission to the user and enables timely tool management.

[0005]

In order to achieve the above object, the present invention provides a personal computer (PC) having an ID reading and writing function and an ID element attached to a tool, and a pot in which the tool is housed. Number and tool number, tool length compensation data, tool radius compensation data, tool status, tool life time, tool usage time and other information about the tool are written and stored to store and manage the tool, and it is mounted on the spindle side. The necessary information stored in the ID element of the tool is numerically controlled using the control code.
C) side, the tool data of the machining program on the M / C side is corrected, and on the M / C side, the information of the tool being machined and the information such as the tool damage are transmitted to the PC side each time by the control code, It is characterized by a tool management method using a tool ID by the PC that rewrites the tool information stored in the PC.

[0006]

The various information regarding the tool is stored in advance in the PC and the ID element of the tool. Information is normally transmitted between the PC and the M / C by a control code that is generally used. When the desired tool is mounted on the spindle based on the machining program, the ID element of the tool is read and the PC
Information about the tool stored in it is recalled for operating the PC. This information is transmitted to the M / C via the control code. Thereby, the information about the tool in the M / C is rewritten, and the predetermined machining is performed based on the rewritten tool content. Also, by storing the information of many tools in the PC in advance,
The desired management of unused spare tools is done by PC operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In a PC (personal computer) 1, a PC main body 2, a read / write head (R / W) 3 for reading information in the ID element and rewriting the information, an ID control device 4, etc. are integrally arranged. Is set up. On the other hand, the ID element 7 is integrally attached to, for example, the pull stud 6 of the tool 5.
On the other hand, a control code 9 for communication transmission using DC1 to DC4 is connected between the numerically controlled machine tool (M / C) 8 and the PC1. DC1 to DC4 are generally used as simple communication codes for communicating "sending information", "sending completed" and the like. As shown in FIG. 1, when the tool 5 is mounted in the spindle 10, the ID element 7 and the PC 1 side are electrically connected to each other.
The tool information during machining 8 is sent to the PC 1 side via the control code 9.

Tool information of the tool 5 is stored in the PC 1 in advance. FIG. 2 shows an example thereof. As the tool information, for example, the pot number into which the tool is inserted, the tool number,
Tool length correction data, tool diameter correction data, tool stator 2, tool life time, tool usage time, etc. can be increased. These pieces of information are newly stored or rewritten and stored in the PC body 2 of the PC 1 by an input command, and are called to the M / C side or the like by a necessary output command. Also, the tool 5
At least a tool number is stored in the ID element 7 of.

Next, the operation of this embodiment will be described with reference to the flow charts of FIGS. As described above, the tool information (shown in FIG. 2) regarding the tool 5 is previously input to the ID element 7 of the PC 1 and the tool 5 (step 10).
0) It is stored (step 101). Next, the desired tool 5 is mounted in the spindle 10 by the machining program (step 102). Information such as the tool number stored in the ID element 7 of the tool 5 is input to the PC 1 (step 10
3). In response to an input command from the attached tool 5, information regarding the tool 5 is called from the PC 1 (step 104). The called tool information is sent to the M / C 8 side via the control code 9 (step 10).
5). Information on the tool 5 mounted on the M / C 8 is transmitted (step 106). Based on this information, each data related to the tool in the machining program is rewritten on the M / C 8 side (step 107). Predetermined processing is performed by the processing program in which the data has been rewritten (step 10).
8). Information on the tool 5 being machined by the M / C 8 and information during machining such as damage to the tool 5 are extracted (step 109), and control code communication (step 110).
Thus, the data is communicated to the PC 1 side and the stored data is rewritten and stored (step 111). On the other hand, when performing the spare tool management (112), the tool information of the spare tool is set to P.
Tool management is performed by pre-storing in C1 and using a general management method. As described above, by using the PC1 having the general structure, the tool information is transmitted to the M / C8 side in a timely manner, and the information of the tool 5 being machined on the M / C8 side is transmitted to the PC1 side in a timely manner and stored. It

[0010]

According to the present invention, the following effects can be obtained. (1) P that is generally used without using a CPU or the like
Tool management is easily performed by C. Thereby, the tool management cost can be reduced. (2) Communication between the PC and the M / C side is performed by a general control code without using a special communication method. (3) Since the tool management is performed by the PC and the control code, it is possible to easily retrofit not only the new M / C but also the existing M / C. (4) By storing the data of the spare tool in the PC,
Tool management such as the quantity, model, shape and life of spare tools can be easily performed.
