Abstract
A cutting tool and a cutting insert, each of which including a base surface and an anti-slip arrangement adjacent thereto. Each anti-slip arrangement includes an actuator surface and non-parallel first and second abutment surfaces, and the actuator surface of the cutting tool is a surface of a clamp of the cutting tool. The cutting insert is mounted on the cutting tool via engagement of the base surfaces thereof and the clamp is operable to bias the actuator surfaces against each other and thereby force the first and second abutment surfaces against each other, for preventing slippage of the cutting insert along the tool's base surface.
Claims23
A tool having a cutting direction and comprising:
- an insert seating region comprising a tool base surface, tool inner and peripheral regions located on opposing sides of the insert seating region, the cutting direction being defined as extending from the tool inner region towards the tool peripheral region, and a tool anti-slip arrangement;
- the tool anti-slip arrangement comprising first and second tool abutment surfaces formed adjacent to the tool base surface and being non-parallel to each other and to the tool base surface, and a clamp located at the tool inner region and comprising a tool actuator surface lying in a tool actuator surface plane which is oriented transverse to the tool base surface;
- wherein pairs of closest points of the first and second tool abutment surfaces that lie within respective common tool abutment surface planes which are parallel to the tool actuator surface plane, are a predetermined distance apart;
- at least one of the predetermined distances has a greater magnitude than another predetermined distance which is associated with a pair of points further spaced from the tool actuator surface plane;
- and
- the clamp is configured for force application in the cutting direction via the tool actuator surface.
