CNC machining is developing towards high speed and high efficiency. This includes the speed control of CNC machining. To make full use of the effective working stroke, the moving parts must be accelerated to a high-speed stroke in a very short time and stopped instantly during the high-speed stroke. This is why the speed control of Dongguan CNC machining is necessary. Based on the open control idea, we propose a method that can automatically accelerate and decelerate the motion of the CNC machine tool according to any curve. This method pushes the automatic acceleration and deceleration control from the traditional fixed mode to the new flexible mode, and explores a new way to effectively improve the dynamic performance of CNC machine tools. 1. Flexible acceleration and deceleration control In Dongguan CNC machining, the specific automatic speed control function is usually directly realized by the system program. In this way, it is necessary to change the system's acceleration and deceleration characteristics or add and subtract control to modify the CNC program, so ordinary users cannot make CNC machine tools have better acceleration and deceleration performance according to their own wishes. Therefore, the flexible acceleration and deceleration control method we proposed adopts the principle of the database, and divides the acceleration and deceleration control into two parts: acceleration and deceleration description and implementation, and separates the acceleration and deceleration description from the system program. In the numerical control system software, a general control channel that has nothing to do with the content of the acceleration and deceleration database is designed, and the acceleration and deceleration calculation and trajectory control are independently completed by it. 2. Flexible automatic acceleration control Set the acceleration curve, analytical curve and non-analytic curve, and store them in the acceleration and deceleration curve library in the form of a number table as a model. 3. Flexible automatic deceleration control For acceleration control, it is stored in the acceleration and deceleration curve library in the form of a number table as a model. Reasonable automatic acceleration and deceleration control is an important link to ensure the dynamic performance of CNC machine tools. The traditional automatic acceleration and deceleration control based on a fixed curve lacks flexibility, and it is difficult to ensure that the acceleration and deceleration process matches the performance of the machine tool, and it is difficult to achieve better dynamic characteristics of the machine tool movement.

As the name suggests, lathe parts are products processed by lathes. Lathe parts can be divided into many types according to different types of lathes. Common ones are automatic lathe parts, CNC lathe parts, instrument lathe parts and so on. The hardware materials used in the lathe parts are copper, iron, aluminum, stainless steel and so on. The more common processing areas are Shenzhen, Dongguan and surrounding areas. Lathe parts have a wide range of applications, involving industries such as electronic appliances, hardware tools, toys, and plastics. Compared with other solid parts, its main feature is precision, and the tolerance can reach plus or minus 0.01MM, or even more accurate. Of course, its price is relatively much higher than other sturdy parts. Automatic lathe parts are parts processed by automatic lathes. The processing diameter is 20mm and the processing length is 90mm. Because the processed parts are small and the speed is high, the price is relatively low, the precision of the processing is high, and the tolerance can be controlled within plus or minus 0.01mm . CNC lathe parts are parts processed by CNC lathes. The processing diameter can reach 60, the processing length is 300mm, the processing parts are large, the shape is complex, and the precision is high. It can be turned several times with a tolerance of plus or minus 0.002mm. Products made of stainless steel have advantages. Because the machines are expensive and the processing efficiency is low, the processing costs are relatively high. The reason why the processing cost of lathe parts is higher than that of other hardware parts is because of the processing technology of turning, which has high precision, low speed and low output. After a large part of the lathe parts are processed on the machine, they need to be processed twice to meet the functional requirements, such as: slot milling, drilling, milling, chamfering and so on.
