  • A New Milling 101: Milling Forces and Formulas

    Mar 21, 2011Ron Davis, Manager, Training and Development, WIDIA Products Group. In milling, cutting forces are exerted in three planes to deform and shear away material in the form of a chip. Tangential cutting forces overcome the resistance to rotation and account for 70 perent of the total force. Feed forces account for 20 percent of the total force.

  • Collet vs. End Mill Holder

    Feb 11, 2020End mill holders are for weldon shank end mills. They use a set screw to tighten down on a recess flat on the end mill. You must use an end mill with a weldon shank. The weldon shank won't slip (spin) like it could in a collet. So you can use a weldon shank end mill in a collet but you can't use a straight shank end mill in an end mill holder.

    Dec 25, 2020The greater the helix angle of the end mill, the longer the contact length between the work piece and the cutting edge. This can reduce the load per unit length of the cutting edge, so the tool life can be extended. But at the same time, the cutting resistance will increase, so you must consider using a tool holder with high clamping rigidity.
