The Study on Accuracy Control System with the Three Datum Planes in Fixture Design

Article Preview

Abstract:

The fixture accuracy is controlled on the three datum planes with fixture or compound body used as design object, with structure of parts and the machine accuracy used as the target required, with cutting tool and the machine datum plane mounted fixture used as viewed body. The assistance datum plane is towards the machine locating planes mounted fixture, and it is parallel to the cutting speed of tools; the assistance datum plane (or line) is perpendicular to the assistance datum plane, and it is passing through center line of tool (or fixture);the assistance datum plane is through the single point of fixture , perpendicular to both two.
