The tool path position can be set manually using the position slider found at the bottom of the Simulation View.The Position dock will tell you where the tool is in 3D space.

THREAD CUTTING & FORMING - Concordia University

Materials: any material sufficiently plastic can be rolled. (can with stand the forces of cold forming without disintegration) Rollability is the feature required from metal during the rolling process steel not convenient to roll because it has the tendency to harden while worked on the surface. However, this tendency assures high hardness of the

Gyratory Crusher - an overview | ScienceDirect Topics

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...
