Question
A straight turning operation is carried out using a single point cutting tool on an AISI 1020 steel rod. The feed is mm/rev and the depth of cut is mm. The tool has a side cutting edge angle of . The uncut chip thickness (in mm) is _______
Correct answer
0.08 to 0.12
Solution
In a turning operation, the uncut chip thickness () is related to the feed () and the side cutting edge angle () by the following geometric relationship:Alternatively, if using the principal cutting edge angle (), where :Given:
Feed, mm/rev
Side cutting edge angle, Calculation:The uncut chip thickness is mm.
Feed, mm/rev
Side cutting edge angle, Calculation:The uncut chip thickness is mm.
