CNC machining should follow the principles when designing the process
1. The principle of one-time positioning
The full play of energy efficiency of CNC machining is not only closely related to the processing requirements, but also the influence of the process is very important, which requires the adaptive design of the process according to the actual situation. In this link, it is necessary to ensure a high degree of uniformity among the various process projects, adhere to the principle of one-time positioning, which is in fact, a strict control of the processing process. In a unified production process environment, this principle enables parts to participate in as many machining operations as possible in a simple process. This not only provides greater centralization, but also shortens the machining process and reduces error values to a smaller range. Especially in the process of machining coaxial pores, the error should be considered, because each time the machining accuracy value in the positioning link will change to a certain extent, the existence of this error value will directly lead to the decline of machining accuracy, so it must be positioned as much as possible to reduce the error value.
2. Step-by-step fine processing principle
Although CNC machining has strong application advantages, in order to further improve its processing accuracy, it is necessary to adhere to the gradual fine machining process as the main body in process design. The reason for fine machining in the subsequent stage is because starting from the initial demand of simple parts, it can provide a buffer energy reserve stage for CNC machining, which can also effectively improve the processing efficiency, and then the finishing of the parts can achieve maximum utilization of the amount of machining technology. In the preliminary roughing process, the operator needs to reduce the workload of the tool according to the actual situation, so that the machining allowance can be effectively controlled, and the working energy efficiency inevitably shows an upward trend. When advancing machining operations to subsequent finishing, it is necessary to treat issues such as changes in the shape of parts due to roughing properly. After taking this factor into account, it is possible to rework the deformed part to meet the application standard by relying on finishing.
3. The principle of near and far
In the process design of CNC machining, in order to ensure that the energy efficiency of the tool application reaches the best state, it is necessary to take the principle of far and near as the main design idea. This is because it is necessary to set the pass position and path during the machining process, and only by ensuring the shortest distance can the machining efficiency be further improved. Therefore, when designing the process, it is very important to plan the tool movement route and distance. When the tool can be completed by relying on short-distance movement when in use, its precision control role can be fully exerted. That is to say, in the CNC machining process, it is necessary to select the part closest to the tool, then gradually advance to the distant part, and finally expand the range of the machining operation to the farthest distance. Taking this as a benchmark for passing can realize reasonable savings in processing resources, which can not only improve processing efficiency, but also fully ensure machining accuracy.
