This type of cut requires lower forces and is preferred for roughing cuts. In climb milling, the work moves with the rotation of the cutter. This produces a better finish. It is not recommended if the workpiece cannot be held securely or cannot support high forces. Conventional Milling Climb MIlling Calculating Speeds and Feeds Cutting speed refers to the speed at which the tool point of the cutter moves with respect to the work measured in feet per minute.
Feed is the rate at which the work moves into the cutter measured in feed per tooth revolution.
Feeds and speeds affect the time to finish a cut, tool life, finish of the machined surface and power required of the machine. The cutting speed is mostly determined by the material to be cut and the material of the tool. To find the right speed for any task, refer to the Machinery's Handbook or other reference. To calculate the proper spindle speed, divide the desired cutting speed by the circumference of the tool expressed in feet. The feed rate depends on the width and depth of cut, finish desired and many other variables.
