Compared with precision machining, precision machining has significant advantages in terms of material removal rate and economic efficiency. The laser plasma process, which is not commonly seen in the market, can achieve high material cutting under high energy conditions compared to precision mechanical processing. There are also issues with the accuracy and size of the processed workpiece. However, the initially proposed non cutting process is more suitable for the production of a large number of workpieces. In order to obtain qualified workpieces, subsequent machining and cutting must be carried out. It seems that in order to achieve high precision of the workpiece, only precision machining technology is more suitable. Nowadays, precision machining is widely used, and the trend of small-scale production has further promoted the development of precision machining. With the continuous improvement of requirements for the size and accuracy of workpieces, it has also expanded the scope of precision machining. When turning, the use of a lathe is a necessary process. In addition, more precise machining such as drilling and grinding can be achieved on the same machine tool. Precision machining is not an easy machining technology, which is influenced by many factors and involves a wide range of aspects. It requires a significant investment and products have strong personalities, which are enough to become factors that affect precision machining.
