Abstract
The machining process planning design and machine tool fixture design plays a very important role in parts manufacturing. Make feasible machining technology route and design reasonable fixture can ensure machining quality, product qualified. The design of the content can be divided into design for mechanical machining and machine fixture design two parts. First the B6065 planer promote frame parts are analyzed in detail, understanding the role and requirements of the processing, formulation, analysis, comparison and determine the process scheme, machining allowance and the process dimensions were determined, choose suitable processing equipment, to determine the cutting parameters, calculate the basic work processing required. And by using the basic principle and method of fixture design, fixture design scheme proposed, aiming at the slot milling machining process and drilling process three sets of special fixture design. Processing technology of the design is reasonable, feasible, high efficiency, labor saving fixture, can meet the processing requirements of parts, ensure the machining quality.
