Description

This free online course on Finishing Processes and CNC Machine starts with surface finish in machining. Surface finish requirement may be as important as the desired dimensional accuracy. Next we will discuss CNC machines and CNC programming. Numerical control machining is a class of machining in the tool industry. It enables an operator to communicate with the machine tools through numerically encoded instructions.

Next we will discuss advanced machining processes. Machining is a process of removing the material from a workpiece to create a part of desired shape, size and surface finish. In traditional machining, the tool makes physical contact with the workpiece and produces contact stresses which cause the fracture on the surface of the workpiece. A distinguishing feature of advanced machining processes is that they do not use a well-guided wedge shaped tool to remove the material relative to the workpiece.

Finally we will talk about chemical machining. Material is removed by using chemical etchant. There are several variants of the process: chemical blanking, chemical milling, photochemical machining and chemical en raving. Cleaning is first done before chemical machining any workpiece. The surface of the workpiece should be cleaned of sand and grease. Masking is a protective coating applied on the work surface that is not going to be etched.
