Abrasive tool inserts with diminished residual tensile stresses and their production

摘要

An abrasive tool insert includes (a) a substrate having a support face that includes (1) an inner support table, (2) an outer shoulder having a width, S_w, and (3) a downwardly sloping interface from the support table to the shoulder, which interface has a slope angle, S_a. A continuous abrasive layer, integrally formed on the substrate support face, includes (1) a center having a height, D_c, (2) a diameter, D_d, (3) a periphery having a height, D_p, in contact with the shoulder and which periphery forms a cutting edge. S_w:D_d ranges from between 0 and about 0.5. For each S_a and S_w:D_d, D_c:D_p is selected so as to diminish residual stress in the abrasive layer.
