Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing CNC machine tool is a contact measuring device, which can only measure the workpiece statically and cannot be combined with the CNC system to provide online measurement. The processing is separated from the process and is completed by different staff, resulting in process design. To solve the problem of cycle extension, provide a CNC lathe intelligent control system and its control method with the advantages of reasonable configuration, high degree of automation, low cost, easy combination with existing lathes, and effective shortening of process design cycle.

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] figure 1 The composition of the control system of the present invention is given. It has an upper computer 1, the upper computer 1 is a computer; the lower computer 2 is the control device on the CNC lathe, which is a DSP chip of the model TMS320LF2407A; the upper computer 1 and the lower computer 2 are connected through USB serial communication 3. It uses A high-speed USB with parallel bus and local DMA transfer capability, its model is PDIUSBD12. The upper computer 1 can extract CAD graphics information, intelligently plan tool paths, optimize process parameter databases, generate NC codes, and process simulations through corresponding software. The lower computer 2 realizes on-line measurement through the photoelectric detection device 3, controls the operation of the motor, and compensates the processing amount of the tool by the linear arc i...

Abstract

The intelligent control system of NC machine tool is formed from NC machine tool, upper position machine and lower position machine. The upper position machine and lower position machine are formed into open control system, between upper position machine and lower position machine it utilizes USB to make serial communication, on the NC machine tool a photoelectric detection device is mounted and connected with lower position machine. Said system can implement on-line detection.

Description

technical field [0001] The invention relates to a numerically controlled lathe, in particular to an intelligent control system and a control method for the numerically controlled lathe. Background technique [0002] Since the numerical control system was invented in the 1950s, it has experienced the development process from the hard-wired numerical control device NC to the computer-based CNC. The open architecture based on the computer makes the numerical control system have better versatility, flexibility, adaptability and scalability. And develop in the direction of intelligence and networking. High-end CNC machine tools have the function of integrating processing and measurement. At present, they are mainly used for boring and milling machines with contact probe probes or expensive non-contact laser measurement systems. Measurement and sensing systems used in turning and grinding rotary processing machine tools Most are contact measuring devices. And these measuring dev...
