High speed machining technology has increased many production efficiencies in the machining and manufacturing industries. High speed machining is capable of achieving great structural integrity and improved machining accuracy and precision compared to traditional machining methods. This technology has enabled the transition from drawn engineering parts and machined parts to parts that are produced in a much more efficient and cost effective manner. High speed machining also offers many advantages such as higher surface finish, improved part accuracy, and faster cycle time.
High speed machining technology often referred to as CNC machining or rapid machining is the machining process that utilizes very high speeds and feeds to achieve maximum productivity while maintaining a high level of quality. High speed machining typically involves the use of CNC (Computer Numerical Control) machines to quickly produce a variety of parts with high accuracy and finish quality. In order to correctly utilize high speed machining, the CNC machine must be properly set up and operated correctly in accordance with the part and tooling design as well as the material properties.
The first step in high speed machining is the selection of the correct cutting tool for the job. There are many types of tool materials available for use in high speed machining, including coated carbide, cooled carbide, and diamond-coated cutting tools. Selection of the appropriate cutting tools is essential to achieve the required accuracy and cutting speed.
The second step in high speed machining is the selection of the correct machine and cutting parameters. It is essential to correctly identify the correct speed for the cutting tool and the fixturing that will be used to secure the part being machined. Fixturing and tooling designs that maximize rigidity and support are essential in high speed machining in order to reduce vibration and avoid tool breakage.
The third step in high speed machining is selecting the appropriate material for the job. There are many types of materials that are well suited for high speed machining, including aluminum, stainless steel, titanium, and composites. The selection of the right material depends on the design and application of the parts being machined. The material properties must be properly analyzed in order to select the best cutting parameters and to ensure the desired accuracy and machining speed is achieved.
The fourth step in high speed machining is programming the CNC machine to follow the cutting parameters that have been chosen. This usually involves the use of computer-aided machining (CAM) which is a software used to program the CNC machine. CAM is essential to ensure the programmed motions and cutting parameters are followed accurately and efficiently.
The fifth step in high speed machining is monitoring the process to ensure the parts are being produced to the desired accuracy. This involves the use of various monitoring devices such as micrometers, calipers, and optical comparators to ensure accuracy is maintained to the limits specified by the customer or application.
High speed machining technology has been used successfully in many industries and has revolutionized the production process with its increased productivity and accuracy as well as cost savings. When properly implemented, high speed machining can offer great advantages over traditional machining methods.
