Intelligent process design is the key and foundation of intelligent manufacturing technology.In order to improve the efficiency of process design,an intelligent process design method based on parametric process template was proposed.The basic idea was to use parametric method to express the variable information in the process template through parameters,and the parametric relationship between process information,process parameters and part parameters was established by means of parameter expression and fusion rules,so as to realize process intelligent design based on parameter driving.The expression of process,parameters and rules in the parametric process template method was focused on,and the process reasoning process based on the parametric process template was discussed in detail.Finally,taking the spinning process design of cylindrical parts as an example,the intelligent process design was verified.It is shown that this method is easy to realize and efficient.
