Improving and Enhancing Surface Quality of CNC-machined Parts
Cutting technology is a key component in the manufacturing process of CNC-machined parts. It is essential for improving and enhancing the surface quality of machined parts. The desired surface quality goals must be established before any manufacturing process begins, in order to effectively reach them. This paper will focus on laser cutting, EDM die sinking, and milling to discuss the various cutting methods used to improve and enhance the surface quality of CNC-machined parts.
One of the most common cutting technologies used in CNC-machining is laser cutting. Laser cutting uses high-powered beams of light to achieve high precision cut lines. This cutting method has been proven to significantly improve the surface quality of the parts by providing an improved surface finish and finer feature resolution. Additionally, laser cutting can produce complex shapes and have the ability to produce close tolerance machined parts. It is also more cost-effective than other cutting methods as less material waste is produced.
EDM die sinking is also a cutting method used to improve the surface quality of CNC-machined parts. This cutting method is ideal for machining high-precision parts, since parts with complex shapes, tight tolerances and fine surface finishes can be machined easily. The leading edge of the die can quickly sink into the material, providing a relatively smooth surface finish to the final machined part. The absence of cutting friction also helps to reduce the presence of heat affected zones on the part’s surface, which can result in improved material properties. However, EDM die sinking is a slower process than other cutting methods.
Milling is another cutting technology commonly used to improve the surface quality of CNC-machined parts. The use of multiple cutting edges and high grinding speeds in milling can improve the surface finish of machined parts. Additionally, milling can produce highly efficient and accurate parts with a wide range of shapes and sizes. Furthermore, it does not require additional heat input, as opposed to laser or EDM cutting methods.
In conclusion, cutting technology is a key component of the manufacturing process in achieving desired outcomes for CNC-machined parts. Three of the most common cutting methods used in CNC-machining are laser cutting, EDM die sinking, and milling. These cutting methods can provide improved surface finish, finer feature resolutions, and improved material properties. In order to achieve the best results, a good understanding of each cutting method’s properties and limitations is essential.
