Positioneering (Engineering Science of Positioning Workpieces - Weldments - So That Production and Quality Is Improved) 1st Ed.

Postioneering is the engineering science of positioning workpieces, usually weldments, so that production is increased, quality is improved and manufacturing costs are lowered. Positioneering is the technique of positioning a weldment to get higher production, better welds, and lower costs. This is a basic study and where it is needed, basic physical mechanics, mathematics, etc. will be included and examples given so it will be clear exactly how such sciences effect Positioneering. With a full understanding of the principles on which the science of Positioning is based, you will readily accept specific problems and easily determine solutions to the problems.
