Abstract: Under networked collaborative manufacturing, the relationship between product task programming and manufacturing resources configuration was discussed. Then a model of task granularity of mechanical product manufacturing was set up. To deal with the influencing factors such as production cost supported by networked collaborative manufacturing, product function component & process method, and task manufacturing cycle of mechanical product, from macro viewpoint, the issue of task granularity planning of product manufacturing was analyzed by integrating qualitative and quantitative methods, and then the mathematical expressions of some relationships reflecting the layout of manufacturing tasks were presented. The quantitative relationships between task granularity and three influencing ingredients were seriatim established so as to seek the optimal values of task granularity. According to the expressions, many elicitations meaningful to task programming under networked manufacturing were achieved. So the task granularity was concretely programmed under idiographic surroundings, which could provide fundamentals for optimizing configuration of networked manufacturing resources.
