Title
(EN) Apparatus for breaking chips
Abstract
(EN)
Apparatus for breaking chips is disclosed in which the chip generated during cutting is broken into small pieces by increasing the shear strain at the shear plane, which is the joint between the chip and the workpiece, until fracture occurs at the shear plane. This is achieved by forming a chip generated during cutting into a lever by guiding the chip using an arcuate surface (97) inclined to the tool cutting edge (19).
