Contour Surface Milling - an overview | ScienceDirect Topics

Considerable time (49–72%) is spent in contour surface milling for the design surfaces (the surfaces to be machined) of molds and die. Design changes in structural geometry due to functional considerations may affect manufacturing cost significantly, and vice versa. Among different types of machining operations, contour surface milling is the ...

Tips for Better Surface Finish in Milling Operation ...

2022-2-9 · Other tips for good finish in milling are: i. Use climb or down milling. In conventional or up milling, the cutting edge starts with zero chip thickness and digs into the material; creating lot of rubbing action before the edge can actually get a bite. This rubbing action causes pressure and heat build-up at the finished surface.
