New Informational Symbols for Holding and Driving Mechanisms Used for Machining Shafts Between Centers

Abstract

The paper presents new informational symbols for existing holding and driving elements and mechanisms used for machining cylindrical parts between centers. These informational symbols are not shown in technical literature. Presented informational symbols respect the following technological needs: to suggest the shape of locating element; to indicate the number of degrees of freedom retained to the workpiece through locating; to indicate the type of driving mechanism; to depict the characteristics of preliminary and final clamping mechanisms. These informational symbols are indicated next to technological bases of the shafts that are planes of frontal surfaces and axes of centering holes.
