Programming Methods for Combined Additive-Subtractive Processing

Recent revolutionary changes in the field of engineering have led to the emergence of truly breakthrough technologies based on combined additive-subtractive processing. Up until now 3D part formation has been performed using 3D printers which, however, have limitations with regards to the dimensions and accuracy of the printed pieces. CNC machines and robots, if equipped with appropriate tools, can solve the problem of dimensions, while machining work can improve the accuracy. Combined operations allow the generation of workpieces on CNC machines by depositing various materials to form multilayered surfaces as well as machining to produce parts in accordance with drawings requirements. This results in a significant reduction in material and labour intensity of the manufacturing process. This paper describes programming methods of combined additive-subtractive operations.
