Abstract: In this paper, a typical crankshaft machining of piston compressor is taken as the research object. Based on system handing analysis (SHA), according to a series of problems existed in current actual production process, such as excessive materials handling time, work in process (WIP) overstock, unreasonable production layout, low utilisation rate of equipment, high labour cost, etc.., the process flow diagram method is adopted to research processing, handling, parking, waiting and checking processes in crankshaft production logistics. Reliable optimisation of the production process is achieved via collection and analyses of time data in process flow. Through the researches on process flow optimisation of crankshaft machining considering production logistics, the unreasonable processing technology of the crankshaft production and processing workshop is changed; through detailed analyses and optimisation, process flow time of crankshaft production and processing is saved, the production efficiency is improved and the cost is reduced. The work done in this paper can provide reference for other products in process flow optimisation of machining.

Keywords: production logistics; crankshaft machining; process flow diagram method; optimisation; system handling analysis; SHA.
