Main Article Content
Abstract
The change of tool cutting edge angle when machining spherical surfaces of parts on a CNC lathe and in combination machining is analyzed. Formulas for determining the roughness parameter and the angle of contact of the cutting tool moving along a spherical surface are given. The change of tool cutting edge angles on transitions of piercing and nursing when machining a spherical surface with a rotating cutting tool with a translational feed motion is considered.
