Machining Processes: Finishing Processes and CNC Machine

Learn what a Computer Numerical Controlled (CNC) Machine does and is used for during the manufacturing process.

Publisher: NPTEL
This course is based on the finishing processes produced by a CNC machine. These machines are primarily used in the manufacturing industries like mills and we will focus on the services it provides in these industries. On top of learning about the type of finishes this machine can achieve, you will also learn the more fundamental part of programming the machine. This is vital for an operator to know.

Description

We begin this course at the end. At the end of the production process that is! The first part of this course will teach you about surface finish and how the CNC machine is programmed to meet the exact dimensions demanded by the operator. This leads on nicely to the programming of a CNC machine including why it is important and how to work with it.

Advanced machining processes is next on our agenda as we move on to the second part of this course. Machining is a process that involves removing material from a workpiece to create the desired shape, size and/or 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.

The final part of this course talks about chemical machining. Material is removed by using a chemical etchant. There are several variants of the process: chemical blanking, chemical milling, photochemical machining and chemical engraving. This course will teach you about many different types of finishing processes, as you can see. Through using a CNC machine, advanced machining processes and chemical machining processes, you will learn all you need t know about finishing processes in the manufacturing industry.
