Special-shaped CNC machining

CNC Machining is the 1 method of using computer numerical control technology to control machine tools for machining. It realizes the automatic control of material cutting, drilling, milling and other processing operations by transforming the design drawings of the product into the instructions of the machine tool movement.

Traditional CNC machining is usually processed for products with regular shapes and uniform sizes, such as metal parts and plastic parts. However, in some special occasions, it is necessary to process products with irregular shapes and sizes, which requires special-shaped CNC machining technology.

Special-shaped CNC machining is the 1 special processing technology for non-regular shape and non-uniform size parts. In the traditional processing method, these irregular parts usually need to use the traditional manual processing method, which is inefficient and difficult to guarantee the accuracy. The special-shaped CNC machining can accurately control the motion trajectory and processing parameters of the machine tool through computer programming, and can achieve efficient and accurate processing of special-shaped parts.

Special-shaped CNC machining usually needs to convert the design drawings of the product into a three-dimensional model in CAD software, and then convert the model into machine tool motion instructions through CAM software. In the programming process, it is necessary to consider the shape characteristics of the product, the physical properties of the material and the requirements of the processing technology. After the preparation is completed, the instructions are loaded into the control system of the machine tool, and the machine tool will perform processing operations according to the instructions.

In the special-shaped CNC machining, common processing methods include milling, cutting and drilling. Milling refers to the cutting of the workpiece by rotating the tool to form the desired shape; cutting refers to the cutting of the workpiece into the desired shape by the movement of the tool; drilling is the machining of the hole of the workpiece by the rotary movement of the tool. Since shaped products usually require a combination of multiple processing methods, instructions for different processing methods need to be properly organized when writing processing instructions.

Special-shaped CNC machining has many advantages over traditional manual machining and traditional CNC machining. First of all, it can greatly reduce the processing time and labor costs and improve production efficiency. Secondly, because the processing process is controlled by a computer, the processing accuracy can be effectively guaranteed, avoiding the influence of human factors on the processing quality. In addition, special-shaped CNC machining can also reduce the scrap rate and improve the controllability of the production process.

In practical applications, special-shaped CNC machining is widely used in aerospace, automotive, electronics, medical equipment and other industries. For example, in the aerospace field, aircraft turbine blades are very typical special-shaped parts. They are complex in shape and strict in size, requiring high-precision machining. Special-shaped CNC machining can meet this processing demand and improve the quality of parts and production efficiency.
