Dividing is the first subgroup under the heading of parting, but is generally
categorized as a “forming technique” since it is often used with
other complementary production processes (cf. Fig. 2.1.2). According
to the definition of the term, dividing is taken to mean the mechanical
separation of workpieces without the creation of chips (non-cutting).
According to DIN 8588, the dividing category includes the subcategories
shear cutting, wedge-action cutting, tearing and breaking
(Fig. 2.1.28). Of these, the shear cutting is the most important in industrial
application.
