Method and apparatus for concurrent multi-user toolpath creation

A method for generating a toolpath includes providing a plurality of machining target models based on a model of an engineering object, assigning the machining target models to CAM clients operated by users, receiving a machining instruction sequence from each CAM client, and machining a part by executing each of the machining instruction sequences on one or more machine tools. The machining instruction sequences may be merged into a single machining instruction sequence before being executed by a machine tool. The machining target models may be created manually or automatically generated. In certain embodiments, the machining target models are generated by spatially partitioning the model of the engineering object. In one embodiment, features that are allocated to a separate machining process are removed from the machining target models. A corresponding apparatus is also disclosed herein.
