1.0 INTRODUCTION TO MANUFACTURING PROCESSES

1.4.1 PROCESSING OPERATIONS

1. Processing operations are the process that changes the geometry, properties, or
appearance of the starting material as shown in Figure 1.6.

2. The process will alter a material’s shape, physical properties, or appearance to add
value.
3. One of the main processing operations is shaping operations, that alter the geometry of
the starting work material.

4. Four Categories of Shaping Processes:

a. Material removal processes - starting material is a ductile or brittle solid. Topics will
be covered in Conventional Machining and Non-conventional Machining.

b. Solidification processes - starting material is a heated liquid or semifluid. Topics will
be covered in Casting Processes and Polymer Processes.

c. Deformation processes - starting material is a ductile solid (commonly metal). Topics

will be covered in Sheet Metal Processes and Bulk Deformation processes.

d. Particulate processing - starting material consists of powders. Topics will be covered
in Powder Processing.
