They are called "worker machines". They have an extremely important position in the equipment manufacturing industry and are widely used. Used in aviation, aerospace, shipbuilding, light industry, automobile, textile and other industries. The CNC system is the core component of CNC machine tools, which largely determines The function and performance of CNC machine tools. As the functions become more powerful, the CNC system is More and more applications in. However, the more powerful the function, the greater the harm caused by failure. Due to failure to diagnose and repair in time or diagnosis Direct and indirect losses caused by improper maintenance and repairs (including damages to blanks, tools, workbenches, machine tools, CNC systems themselves, etc., The damage to the body and the environment and the losses caused by downtime and lost work) are about hundreds of millions of yuan (the output value of the CNC system industry is on the order of tens of billions). In order to reduce these hazards and losses, adopt and implement effective fault diagnosis and maintenance methods to locate the fault and make it possible To quick repair is particularly important. Develop technical standards for fault diagnosis and maintenance of CNC systems, Standardizing the fault diagnosis and maintenance process, fault and maintenance data statistics, etc., has important implications for improving the efficiency of fault diagnosis and maintenance. It can effectively improve the reliability of the CNC system and reduce user losses. Specification for fault diagnosis and maintenance of machine tool numerical control system1 ScopeThis standard specifies the technical requirements for fault diagnosis and maintenance of machine tool numerical control systems. This standard applies to machine tool numerical control systems.2 Terms and definitionsThe following terms and definitions apply to this document. 2.1 Machine CNC System A control system that uses numerical control to control machine tool processing functions. Note 1.Machine tool numerical control systems generally include hardware devices and corresponding software. The machine tool numerical control system is mainly composed of a numerical control device (also called a control unit) and a driving device (Motor drive unit and motor, sensor) and other components. The numerical control device is the main part of the machine tool numerical control system, which mainly includes a microprocessor, a Motion (position) controller, memory, input/output (I/O) and communication interface, man-machine interface (display and keyboard), operating buttons (keys) and other hardware (and/or circuits) and corresponding control software. Note 2.There are multiple classification methods for machine tool numerical control systems. According to different functions, machine tool CNC systems are usually divided into three types. simple type, high-performance type and popular type; According to the different application technology, it can be divided into two kinds of special and general CNC systems; according to the different feedback control forms, it can be divided into open loop control and semi-closed loop control. There are three types of control and closed-loop control; according to the different processing control methods, it can be divided into three types. point control, linear control and contour control. Note 3.Rewrite JB/T 11989-2014, definition 2.1.3. 2.2 malfunction The state in which the CNC system of the machine tool cannot complete the required function. Except for preventive maintenance or other planned actions or lack of external resources. Note 1.The failure is usually caused by the failure of the product itself, but even if the failure does not occur, the failure may exist. Note 2.Rewrite GB/T 2900.13-2008, definition 191-05-01. 2.3 Troubleshooting Actions taken for fault identification, fault location and analysis of the cause of the fault. [GB/T 2900.13-2008, definition 191-07-22] 2.4 malfunction repair Fault repair After the fault is located, the action taken to restore the faulty product to a state where it can complete the required function. Note. Rewrite GB/T 2900.13-2008, definition 191-07-23.3 Machine tool CNC system failure3.1 Overview The machine tool numerical control system often runs in conjunction with its control object (such as machine tool), and there is a complex structure and functional relationship between the two. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 39129-2020_English be delivered?Answer: Upon your order, we will start to translate GB/T 39129-2020_English as soon as possible, and keep you informed of the progress.
