A digital control machine tool is an automatic machine tool that has been equipped with a program control system. It is also known as a digital control machine tool. It is also referred to as a digital control machine tool in some circles. It stands for digital control machine tool, which is also referred to as a program control system or a program control system and controller. This system is capable of performing many different tasks, including programming programs with control codes or other symbolic instructions, decoding those programs, and expressing these programs with coded numbers, to name a few examples. According to a company spokesperson, data is fed into the numerical control device through the use of an information-transporting medium. A machine tool manufacturer based, China, Fourth Machine Tool Co., Ltd. manufactures a variety of machine tools. The arithmetic processing is completed by sending a number of different control signals to the various processors in order to complete the operation. With each signal, the machine tool is instructed to perform a specific action, which automatically shapes and sizes parts according to the drawing's specifications.

This distinction is particularly important when it comes to CNC machine tools, because positioning accuracy can be thought of as the motion accuracy of the machine tool in this context. Machine tools' moving parts are guided through their movements by numerical control devices (NCDs), which are used to guide the machine tool's moving parts. It is necessary to turn off the numerical control device after the machine tool's movements are completed and the machine tool has been turned off. There is a substantial amount of information available.

It is common practice to perform linear motion positioning accuracy tests on machines and worktables when they are not in use to ensure that they are in proper working order. There is a logical consequence to this, in that the accuracy of the measuring instrument must be one to two levels higher than the accuracy of the measurement itself, and vice versa.

All possible errors in multiple positioning are taken into consideration and corrected for during the calculation process as a result of doing so.

The repeat positioning accuracy of a coordinate can be calculated by dividing one-half of the largest difference between three positions by two and assigning positive and negative signs to each half of the resulting fraction, as shown in the example below. It is used to determine the accuracy of axis motion stability and is also the most fundamental and widely used indicator of accuracy. This parameter is used to determine the accuracy of axis motion stability.

Due to the difficulty of determining the precision with which linear motion can be returned to its starting point, this calculation is difficult to perform.

There are numerous types of errors that can be observed in a systematic manner. Backlash and elastic deformation are just a couple of examples. The presence of a significant amount of error has resulted in a significant reduction in the accuracy of both the positioning accuracy and repeat positioning accuracy.

Detecting reverse error in a coordinate axis stroke involves moving the axis a predetermined distance in either the forward or reverse direction in advance, using the stop position as a reference, and then providing it with a specific movement command value in the same direction, causing it to move a predetermined distance in the same direction, as shown in Figure 1. Move the same distance in the opposite direction as you did in the first direction to determine the accuracy of your measurement. Then measure the difference between your stop position and your reference point (the difference between your stop position and your reference point), as shown in the diagram.
