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 X-axis. Adjustment toward X-axis Standard insert Adjustment toward Z-axis Standard insert DNMXTNMX type DNMXTNMX type Corner radius 0.40.8 0.04 mm Corner radius 1.2 :0.05 mm (Not closed to Comer 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 60 70) and is not machined completely. Geometry of adjusted program Classification Taper Angle 6 Comer radius -25 15 -10 -5 0 5 10 15 20-35 40 45 50 55 60-65 70 75-85 90 1.2 0.04 0.03 0.01 0 0.02 0.03 0.04 0.05 0.04 0.04 0.02 0.01 -0.01 0 0.01 0 0.8 0.03 0.02 0.01 0 0.01 0.02 0.03 0.04 0.03 0.03 0.02 0 -0.01 0 0.01 0 0.4 0.02 0.01 0.01 0 0.01 0.01 0.02 0.02 0.02 0.01 0.01 0 -0.01 -0.01 The number +numbers:adjustment of relief angle -numbers:adjustment of drive-in angle (mm) B) Adjusting a Corner R Necessary to maintain a correct comer radius. 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 comer radius in this case. The comer radius of the insert The adjustment amount on the workpiece radius. 'Comer Radius 0.4- Comer Radius 0.8 - V Comer 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 Easy-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 comer radius of a insert The value of corrected comer radius approximation Comer Radius 0.4-) R0.36(mm) Comer Radius 0.8 - R0.76(mm) k Comer Radius 1.2- R1.16(mm) Ex):ln the case of machining a corner 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. A029 TURNING INSERTS
