GENERAL TECHNICAL INFORMATION TURNING AND GROOVING SELECTING INSERTS INSERT WIDTH Insert width strongly affects strength For most efficient machining select the widest possible insert Chipbreaking range depends on insert width A narrow width improves chipbreaking at lower feed rates Wide inserts and strong blades require high forces and feed rates to achieve a frontal clearance angle. TURNING FEED Feed depends on chipbreaking range of the insert Maximum feed depends on insert width and is a function of maximum load High feed with small corner radii may reduce tool life Maximum feed should not exceed the corner radii For better chip formation when grooving feed can be interrupted at small intervals CORNER RADII - LATERAL TURNING Choose large corner radii for long tool life Choose small corner radii to reduce cutting load and lower feed with narrow inserts DEPTH OF CUT Minimum depth of cut equals the corner radii Maximum depth of cut depends on maximum possible load Depth of cut depends on chipbreaking range Large depth of cut causes large deflection and large frontal clearance.. With small depth of cut deflection and frontal clearance may be too small. Maximum depth of cut apmax Wx08 1356
