Shaping precision in machining a screw surface

Automatic control of the static loads in multicontact mechanical systems

“…In reality, however, the discrepancies of the pitch due to technological factors (noted in [15][16][17][18], in par ticular) introduce significant changes in the static load distribution between the contact elements of the multicontact kinematic pair. Pitch errors result in deformation of the contact elements and hence in stress beyond that due to the external force.…”

Lathe turning of complex-shaped parts providing desired surface microrelief

“…On a profile that has no section where β = 0, the initial point is the point with zero β on a circle passing through the generatrix of the part. The number of the conical section (counting from the initial point of the supply) is regarded as the number of the supply incre ment [13,14].…”
