Токарные пластины Mitsubishi TURNING INSERT _ Adjustment of machining programmes for DNMX TNMX types Basic Process) Adjusting Toward X-axis and Z-axis Adjusting the differential between a standard insert and Z-axis I X-axis. Adjustment toward X-axis Standard insert Adjustment toward Z-axis Standard insert DNMX,TNMX type DNMX,TNMX type Comer radius 0.4,0.8: 0.04 mm Comer radius 1.2 0.05 mm (Not closed to Corner R) 0.01mm A) Adjusting a Taper Necessary to maintain a correct taper. Adjust the relief angle toward the normal line. Note) Adjust the angle toward the normal line in the case where the adjustment number is minus (8 =60' 70”) and is not machined completely.

Adjust the work diameter same as the taper to prevent cut-over. The value of adjustment to work R = Work R + the adjustment value No adjusting the corner radius in this case. The corner radius of the insert The adjustment amount on the workpiece radius. ''Corner Radius 0.4-> Corner Radius 0.8 -) Corner Radius 1.2 Work Radius+0.05(mm) Work Radius+0.11(mm) Work Radius+0.14(mm) Ex): In case of machining R 2.0 when using a corner R 1.2 type insert. Geometry of adjusted programme = 2.0 + 0.14 Work radius Adjusted conditions The actual machining geometry In correcting corner radius: . , It is not necessary to adjust the machining programme, however, machining errors can occur within max. The caSy-tO-COrreCt Method ±0.03mm due to correcting by an approximate number. Corner Radius Correction Input the correction number of each corner radius. The value of corrected corner radius = approximation No adjusting the machining the programme in this case. The corner radius of a insert The value of corrected corner radius = approximation ’’Corner Radius 0.4-> R0.36(mm) Corner Radius 0.8 -> R0.76(mm) s Corner Radius 1.2 R1.16(mm) Ex):ln the case of machining a comer with a radius R 2.0 when using an insert with a corner radius R 1.2. Others) The value of correction is same for both DNMX and TNMX. Discriminate them by the size of corner radius. Geometry of adjusted program Mitsubishi Materials 57 TURNING INSERT
