Cut-Off CUTDIA 1 1 CUTDIA2 Introduction TKF type How to Use Main spindle 1) When using main spindle only Maximum cutting diameter is CUTDIA (Fig.1). Even if the cutting edge runs beyond the center line, the insert does not contact the workpiece, since the workpiece falls off. (The clearance between the insert and the workpiece is 0.2 mm) Fig.1 Fig.2 (When the edge is at the center) (When the edge is 1mm beyond the center) 2) When using both main and sub spindles Main spindleIn this case, when the cutting edge runs beyond the center line, the insert will contactSub spindle the workpiece, since the workpiece does not fall off. e.g.) When the cutting edge is programmed to run 1mm beyond the center. Workpiece maximum, CUTDIA2 (Fig.4) = [CUTDIA −1 mm×2] (mm) (The clearance between the insert and the workpiece is 0.2 mm) H Fig.3 Fig.4 (When the edge is at the center) (When the edge is 1mm beyond the center) How to select edge preparation Troubleshooting Countermeasures Lead angle (PSIRR) Edge width Name of chipbreaker Neutral (0°) Yes Narrower Wider S T NB Problems Countermeasures Insert fracture Insert fracture prevention Effective Effective Effective Effective Long cutting time Cutting time reduction Effective Effective Effective Effective Entangled chips Prevention of chipentanglementEffective Effective Effective Large boss remain Small boss remain Effective Effective Effective Ring remain Prevention of(Hollow workpiece)ring remain Effective Effective Effective Deformation of hollowworkpiece (pipe)Preventing deformation Effective Effective Effective H12
