(Note) The recommende ramping feed is 0.05mm/tooth or under.
*1) Using the maximum ramping angle, the distance to reach the maximum depth of cut is as follows:
L= (maximum depth of cut ap/tan %). Maximum depth of cut A type is 15.5mm, B type is 14.8mm.
***2) Corner radius of 1.2mm. For other corner radii, use the following formula. {(cutting edge diameter D1)(corner radius Re)–0.25}2
3) Corner radius of 2.4mm. For other corner radii, use the following formula. {(cutting edge diameter D1)(corner radius Re)– 0.25}2
4) Corner radius of 3.2mm. For other corner radii, use the following formula. {(cutting edge diameter D1)(corner radius Re)– 0.25}2
