For machining operations in which change is a constant, general-purpose endmills can have a value that far exceeds their actual cost. As the name suggests, these endmills are not designed for a specific cutting application or material. Instead, they are tools that can be used for most standard machining jobs.

Interrupted cutting in turning is subjective. While some operators may look at a part with a keyway and a small depth of cut as a heavy interruption, another operator may classify heavy interruptions only as multiple interruptions with a larger depth of cut. The workpiece material, part configuration and features, and depth of cut will all come into play when determining how the interruption will affect the overall process.

Greenleaf C4 In Action
Whenever a discussion turns to standard tools (catalog) vs. specials (custom-designed tools), some interesting distinctions arise. For end users, the distinctions are straightforward. OEMs, job shops, and manufacturers up and down the supply chain—whether in automotive, aerospace or general engineering—want to know what, how soon and how much.

Rake Angles Make or Break Facemilling

Published January 18, 2022

Greenleaf C4 In Action
There are two types of rake angles. The axial rake angle is the angle between the cutting edge and the axis of the cutter. This angle affects the facemilling process in several ways. It directs chip flow and impacts cutting-edge strength. In addition, toolmakers use the axial rake angle to control power consumption, said Nate Peters, senior tool design engineer at Greenleaf Corp. in Saegertown, Pennsylvania.
