SU887059A1 - Turning method - Google Patents

Description

with a pitch of 1 mm, and the swivel caliper establishes from the condition of the possibility of the installation movement of the toolholder in the direction longitudinal with respect to the axis of the workpiece.

Perform the first pass with mm / rev feed. get a surface of 0 50.15 mm, return the cutter to its original position, shift the tool holder relative to the rotary caliper along the workpiece axis by 0.5 mm, the transverse caliper is fed in a radial direction along with the rotary caliper and tool holder from the workpiece 0.075 mm. Perform a second pass with mm / rev feed. As a result, the surface 0 50 mm.

Thus, the proposed method improves processing performance by reducing the time to perform the second pass.

Form m l l a 1 3 about b retep and

The method of turning on, includes two consecutive passes of the cutter relative to the workpiece along a coaxial screw path of the same direction, in which after the first pass they leave an allowance on the side less than the height of the micro unevenness that differs in that, in order to increase productivity, the second pass is performed by moving the cutter along a path that has the same pitch with the path of movement of the incisor along the nerve aisle and is shifted relative to it by half of this step.
