Understanding cutting equations | Cutting Tool Engineering
2014年7月1日 · The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π).
Pros and cons of indexable tools | Cutting Tool Engineering
2016年10月4日 · Cemented-carbide cutting tools have been in use since the late 1920s and are now ubiquitous in the metalcutting world. Around 1950, tools that accept cemented-carbide inserts became common in metalworking and are still considered a basic necessity. Indexable cutters are typically constructed of a steel body that has machined features, allowing for the accurate …
