Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a method for exchanging machining data, etc. with external equipment such as an NCgi device when performing machining work with a numerically controlled (NC) machine tool. The present invention relates to portable data processing and processing devices that are delivered and delivered. (Prior Art) When performing machining work using an NC machining machine, tools used for the machining work are assembled in a machining preparation room and the dimensions of the tools are measured. Then, a correction value for the tool is determined from this dimension and the set value. Next, the assembled tools are transported to the installation position of the NC processing machine and stored in the tool magazine of the NC processing machine, and the correction values are input to the NC device. At the same time, tool data, NC programs, etc. necessary for machining work are input to the NC device. Incidentally, the equipment used when performing the above machining work includes a tool presetter for measuring tool dimensions, an automatic programming device for NC programs, and a host computer for managing machining data and the like. Therefore, the tool correction value determined from the dimensions measured by the tool presetter is input to the NC device and sent to the host computer, and the NC program determined by the NC automatic programming device is input to the NC device. Data is also sent to the host computer, and data is exchanged between external devices. However, each of the external devices has different data transmission protocols and data formats. Therefore, even if an attempt is made to connect and transmit data between these external devices, the data cannot be transmitted even if the devices are simply connected. Furthermore, if a configuration is adopted in which data is transmitted using DNC, the cost will be high. Furthermore, it is conceivable to simplify the system configuration by inputting and outputting data to and from each external device by an operator, but there is a problem in that flexibility decreases when the system is simplified. (Problems to be Solved by the Invention) As described above, data transmission between external devices is not possible, DNC requires high costs, and furthermore, simplifying the system reduces flexibility. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an inexpensive portable data processing device that can transmit data with various external devices and easily adapt to system changes. [Structure of the Invention] (Means for Solving the Problems) The present invention provides a data memory that stores machining data such as tool data and numerical control programs, various transmission protocols and data formats of various external devices, and at least a numerical control program.

Next, the main control section 2 reads the data communication program and executes data transmission with the NC device 38 according to the selected data transmission protocol and data transmission format. In this case, the tool data, drawing number data, NC program, etc. stored in the data memory 4 are sent to the NC device 38. Next, when an instruction to edit the NC program is entered from the keyboard 14, the main control section 2 reads out the NC program editing program according to the control program and issues a command according to this editing program. That is, the NC program stored in the data memory 4 is read out and displayed on the liquid crystal display 13. In this state, when the contents of the edit are key-input from the keyboard 14, the main control section 2 edits the read NC program according to the contents of the edit. In this way, in the above-mentioned embodiment, calculations for correcting the NC program and four arithmetic operations are performed, corrections and changes are made to the NC program, and the transmission protocol is changed between the NC program and each external device connected via the connection unit 15.
