ROUND TOOTH CUTTERS AND METHOD OF DESIGN AND USE

摘要

A device for mechanically removing material from a workpiece or bulk feedstock, thereby creating chips of removed material while producing a new surface on the workpiece or bulk feedstock. The device comprises a body that is rotatable about an axis and at least one round cutting insert that is tangentially mounted on the body. Location of the insert is characterized by a reference plane offset and an insert axis angle. The insert has a cylindrical rake surface on which chips are formed. A planar flank surface is oriented relative to a cutting motion so as to provide clearance between the cutting insert and the surface created by removal of a layer that is converted into chips. A circular cutting edge lies at the intersection of the flank and rake surfaces.

1. A device for removing material from an object, thereby creating one or more chips of removed material while producing a new surface on the object, the device comprising:
a. a body that is rotatable about an axis; b. at least one round cutting insert mounted on the body so that an orientation of the insert is characterized by a reference plane offset and an insert axis, the insert having
i. a rake surface that is outwardly facing relative to an insert axis, for forming a chip;ii. a flank surface that is oriented relative to a cutting motion so as to provide clearance between the cutting insert and a surface created by removal of a layer that is converted into one or more chips; andiii. a circular cutting edge at the intersection of the flank and rake surfaces.
