Numerical control lathe numerical control technology the self-important 'instructions'
Numerical control lathe numerical control technology the self-important 'instructions' release date: 2019 - 07 - 12 clicks: 428 numerical control lathe numerical control technology the self-important & other; Information & throughout; Numerical control lathe with complex working condition of high efficiency and high precision processing technology; High efficiency and high precision machining is the eternal aim of machine tool users, the processing technology as the necessary part of access to high quality parts, its advantages and disadvantages of parts processing quality and efficiency has a direct impact. At present, the machine tool users in machining programming stage due to a lack of understanding of the performance of machine tool body, only consider the geometric constraint relationship between cutter and workpiece process programming, process and parameters selection by habit and experience more. In addition, in the sticklebacks surface parts machining, strong time-varying, and change of cutting load will inspire complex response of the process system, easily lead to instability, scrap parts processing. At present commonly used method to improve the quality of machining is to use & other Processing - Analysis - Measurement - Correction - Rework & throughout; Train of thought, long production period and high cost. With the pursuit of high efficiency and high precision processing, the traditional passive process flow is difficult to give full play to the use efficiency of machine tool. Actually, numerical control lathe machining process and interaction mechanism between process system, to achieve high efficiency and high precision processing, first need to research cutting process and the dynamic interaction mechanism between process system, according to different properties of machine tool, cutting tool and parts processing requirements, the comprehensive technology system characteristics and technological process, considering the physical properties of constraint, is put forward for high efficiency and high precision machining tool path planning and process parameters optimization method, realizes the process system and the optimal matching of nc machining process. Second, the study considering the effects of processing machine adaptive control technology, the servo drive links and numerical control link the development of advanced control strategies, realize multi-source processing parameters on-line measurement, error analysis and compensation, improve the machining efficiency and quality. Understand CNC lathe CNC lathe of numerical control technology is not just that simple, even beginner to understand the following requirements: 1. Numerical control technology development mainly through the six main stages: tube CNC system, CNC system, CNC system of integrated circuits, transistor small computer numerical control system, the microprocessor CNC system, a universal CNC system based on industrial PC. 2. Numerical control lathe machining principle is: first, will be digitized pattern and process of machining parts, written in code and procedures prescribed format processing program; Then the program instruction is input into the CNC machine tool equipment; Then the numerical control device to program ( Code) Decode, after operation, the machine tool servo mechanism of each coordinate and auxiliary control signal, drive the moving parts, machine tool control needed to support movement, the processing of qualified parts. 3. CNC lathe is mainly composed of processing procedures, input devices, CNC system, servo system, auxiliary measuring feedback device, control unit and machine tools of seven parts. 4. Numerical control lathe in machining process can be divided into cutting machine, forming machine, special machine tools and other machine tools; According to the function of control system can be divided into the control of point, linear control of point, profile control of CNC machine tools; According to the servo control mode can be divided into the open loop and closed loop and half closed loop control of CNC lathe. According to the function of the CNC system can be divided into high, medium and low three gears of CNC machine tools. 5. CNC lathes have higher technical requirements for the operation and maintenance personnel, also has higher requirements for cutting tool fixture. Is mainly suitable for small batch and multiple production parts, geometry must be carried out in the manufacturing process of complex parts, a variety of machining parts, must strictly control the tolerance of parts, process design, change of parts, need to the test of all parts. 6. On the market use a lot of numerical control system, programming code programming rules shall, in accordance with the use of nc system programming.
