Abstract

A new version of the fixture for sharpening a twist drill is presented, which is modeled in the Autodesk Inventor Professional program environment. The fixture for sharpening the cutting edges of a twist drill combines two movements out of three that implement sharpening. The wear of the back surface of the twist drill, as a consequence of the cutting process is considered and the sharpening methods are analyzed.
