Abstract:
1. A method of manufacturing a pipe fitting comprising tubular parts, including the following steps: defining functions and constrains including constraints of the pipe fitting; preparing a model of the pipe fitting, based on said functions and constraints; checking that making the pipe fitting is possible, and revising the model if any defects are diagnosed during said checking; defining a machining program for the pipe fitting, including selection of tools, tool trajectories and cutting parameters, using a software and the model; simulating machining the pipe fitting and revising the machining program if any errors are diagnosed during the simulating, and machining the pipe fitting by applying the machining program on a clamped block on a numerically controlled machine tool controlled by the machining program so as to machine an outside surface and an inside surface of the pipe fitting, the inside surface including a bend, wherein the checking step includes checking mechanical strength of the pipe fitting by an automatic computation based on parameters of the model.
