A slower feed rate usually results in a finer surface as more cuts are made for any length of wood. Spindle speed becomes important in the operation of routers, spindle moulders or shapers, and drills. Older and smaller routers often rotate at a fixed spindle speed, usually between 20,000 and 25,000 rpm.
It relates to spindle speed via variables such as cutter diameter (for rotating cutters) or workpiece diameter (for lathe work). SFM is a combination of diameter and the velocity ( RPM ) of the material measured in feet-per-minute as the spindle of a milling machine or lathe . 1 SFM equals 0.00508 surface meter per second (meter per second, or ...
Done -- feed rate, spindle speed and cutting speed have been moved to the cutting speed page. Spindle speed is derived from cutting speed and feed rate is mixed in with it, so cutting speed won the toss. it took a while to get my head around it but I think it's sorted now. Onto the next project, all going well of course. Feed rate and spindle ...
Knee mill or knee-and-column mill refers to any milling machine whose x-y table rides up and down the column on a vertically adjustable knee. This includes Bridgeports. Planer-style mill (Plano Milling)Large mills built in the same configuration as planers except with a milling spindle instead of a planing head. This term is growing dated as ...

Most modern lathes have live tooling, allowing for limited milling operations to take place without having to remove the part from the lathe spindle. Second operations can be completed by using a sub-spindle, which is co-axial to the main spindle, but faces the other direction.

Woodworking milling machine in school workshop Woodworking table saw in a school workshop. These machines are used both in small-scale commercial production of timber products and by hobbyists. Most of these machines may be used on solid timber and on composite products.
