Surface finish on a lathe? - Practical Machinist

Sep 02,2013 cut and surface finish for 40mm#0183;That said,the most common reason for lousy surface finish is insufficient depth of cut.Skim cuts have no place on a lathe,with the exception of hard turning (materials HRC 55+).A typical finishing insert like a CNMG431,DNMG431,or VNMG331,has a 1/64 nose radius.Minimum depth of cut on the final pass should be equal to 2/3 the nose Surface Roughness Conversion ChartSURFACE ROUGHNESS CONVERSION CHART Mactech,Inc. 4079 Pepin Ave. Red Wing,MN 55066 PH 651-388-7117 TOLL FREE 800-328-1488 FAX 651-388-0337 mactechonsite ON-SITE MACHINING SOLUTIONS Surface Roughness Conversion Chart Ra (micrometers) Ra (microinches) RMS CLA (N) Rt N Cut-off Length inch mm 0.025 1 1.1 1 0.3 1 0 Surface Roughness Chart Useful Information cut and surface finish for 40mm#0183;The surface roughness chart is a concept that expresses the amount and extent of deviation of a surface from being perfectly flat.As it is practically impossible to manufacture a completely flat surface on the microscopic level,every surface has a certain value of roughness that can be measured with the use of a profilometer.Depending on the scale of the deviations and the roughness
