Cutting Insert and Tool Having an Anti-Slip Arrangement

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 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.

A tool assembly comprising in combination a tool configured for cutting in a cutting direction and a cutting insert mounted to the tool:

• the tool 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 which is oriented transverse to the insert base surface;
• the cutting insert comprising opposing insert top and base surfaces which are connected by an insert peripheral surface, at least one cutting edge, and an insert anti-slip arrangement formed adjacent to the insert base surface
• the insert anti-slip arrangement comprising first and second insert abutment surfaces which are non-parallel to each other and to the insert base surface, and an insert actuator surface which is oriented transverse to the insert base surface;
• wherein:
• the cutting insert and the tool are configured for a position in which the insert base surface contacts the tool base surface;
• and
• the clamp is configured to bias the tool actuator surface against the insert actuator surface which consequently biases the first and second insert abutment surfaces against the first and second tool abutment surfaces for preventing slippage of the cutting insert along the tool base surface.

A method of clamping a cutting insert to a tool:

• the tool comprising an insert seating region comprising a tool base surface, tool inner and peripheral regions located on opposing sides of the insert seating 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 which is oriented transverse to the tool base surface;
• the cutting insert comprising opposing insert top and base surfaces which are connected by an insert peripheral surface, at least one cutting edge, and an insert anti-slip arrangement formed adjacent to the insert base surface;
• the insert anti-slip arrangement comprising first and second insert abutment surfaces which are non-parallel to each other and to the insert base surface, and an insert actuator surface which is oriented transverse to the insert base surface;
• wherein the method comprises:
• a. mounting the cutting insert on the tool in a position in which the insert base surface contacts the tool base surface;
• and
• b. biasing the clamp's tool actuator surface against the insert actuator surface, thereby biasing the first and second insert abutment surfaces respectively against the first and second tool abutment surfaces for preventing slippage of the cutting insert along the tool base surface.
