Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow T-Slot Milling Cutter - Whitney Tool Company Home | About | Products | Catalog | Technical Info | Custom Tools | News | Contact ©2014 Whitney Tool Company - Specifications are subject to change without notice. 906 R Street, Bedford, IN 47421 - p: 812-275-4491 toll-free: 800-536-1971 Intro to Trochoidal Milling - In The Loupe - Machinist Blog Trochoidal milling is a method of machining used to create a slot wider than the cutting tool’s cutting diameter. This is accomplished using a series of circular cuts known as a trochoidal tool path. A form of High Efficiency Milling (HEM), trochoidal milling leverages high speeds while maintaining a low radial depth of cut (RDOC) and a high axial depth of cut (ADOC).

The phrase speeds and feeds or feeds and speeds refers to two separate velocities in machine tool practice, cutting speed and feed rate. They are often considered as a pair because of their combined effect on the cutting process. Cutting data recommendations - Uddeholm For side milling the same cutting speed as for slot milling can. Axial depth of cut, a: p = 1.5 x D: be used, but the feeds must be adjusted in order to obtain a : suitable average chip thickness. Correction factor for side milling: Divide the cutter diameter with the radial depth of cut. See in the chart below which correction factor, C: f, this: corresponds to, and multiply the chosen feed in the table for slot milling with this factor.

While trying to compute proper feeds and speeds using machinery's Handbook 26th ed. I had good luck with their example (pg 1010 & 1011) for slot milling, but not for face milling and end milling along a corner.(examples 1 & 3) speeds and feeds - practicalmachinist.com
Values are given as a starting point only, adjust feeds/speed to suite your machine For long series cutters reduce feed rates by 50% IPM = inches per minute, for mm per minute multiply IPM by 25.4 Trochoidal Milling - WIDIA
