CNC machining and turning working principle
CNC driving involves the use of CNC lathes or multi -axis CNC driving centers. The manufacturer uses CNC lathes to cut the cylindrical and concentric characteristics on the car. Power lathes combine the vertical milling cutter and drill, which can generate a departure characteristics without changing the platform. Special CNC lathes are usually called Swiss machine tools. It aims to quickly produce small parts with complex characteristics by combining multiple tools and main axes in the machine tools.
CNC material
CNC milling machines and CNC lathes are suitable for similar materials. These include aluminum, brass, bronze, copper, steel, stainless steel, titanium and zinc alloy. These tools are also suitable for plastic and composite materials, such as acetaldehyde, ABS, G-10, and high-performance materials such as Peek or PTFE.
Process analysis
CNC machining craftsmanship of the machining parts involves a wide range of places. The possibility and convenience of programming are proposed by some of the main contents that must be analyzed and reviewed.
1. Size labeling should meet the characteristics of CNC machining
In CNC programming, all points, lines, and planes are based on the original point of programming. Therefore, it is best to give the coordinate size directly on the part of the parts, or try to attract the size with the same benchmark.
2. The conditions of the geometric elements should be complete and accurate
In programming, programmers must fully grasp the geometric parameters of parts contour and the relationship between each geometric element. Because all the geometric elements of the part contour should be defined during automatic programming, the coordinates of each node must be calculated during manual programming. No matter which point is not clear or uncertain, the programming cannot be performed. However, because parts designer considers not weekly or ignored during the design process, there are often incomplete parameters or unclear parameters. Therefore, when reviewing and analyzing the drawings, you must carefully contact the designer in time.
3. Reliable positioning benchmark
In CNC machining, machining processes are often more concentrated, and positioning with the same benchmark is very important. Therefore, some auxiliary references are often required, or some craftsmanship is added to the blank.
4. Unified geometric types or sizes
The shape of the parts and the inner cavity is best to use a unified geometric type or size, which can reduce the number of knives, and may also apply control programs or special programs to shorten the program length. The shape of the parts is as symmetrical as possible, and it is convenient to use the mirror of the CNC machining to program the process function to save programming time.
CNC programming
CNC machining procedures are divided into manual (manual) programming and automatic programming. Manual programming, the entire content of the program is written by the instruction format specified by the artificial CNC system. Automatic programming is computer programming, which can be divided into automatic programming methods based on language and painting. However, no matter what kind of automatic programming method is adopted, the corresponding supporting hardware and software are needed.
CNC use case and industry
CNC milling machine is the main force of the manufacturing, because they are accurate and repeated. This means that they are the ideal choice for fast prototype production and small batches to mass production. The versatility of their materials makes it an ideal choice for almost any job.
CNC lathes are also widely used. The use of lathes for production also requires fewer additional operation settings, which makes them an effective choice for a series of use cases. The shape of the part and the specified tolerance of the parts usually determine which of the two methods -concentric parts with the lathe and the angle that needs to be milled.
