Description

technical field [0001] The invention belongs to the field of machine tool design, and in particular relates to a compound manufacturing machine tool with parallel addition and subtraction materials. Background technique [0002] After decades of development, additive manufacturing technology has shown great advantages over traditional processing methods in the manufacture of complex structural parts. Due to its short manufacturing cycle, high automation, and low material consumption, this technology has been more and more widely used. However, at present, this technology still has disadvantages such as relatively poor surface quality, low dimensional accuracy, and low density of parts materials. The processed parts are difficult to be directly used in practical applications. It is necessary to use subtractive manufacturing methods such as turning, milling, and grinding to perform subtractive manufacturing to achieve the required surface quality and dimensional accuracy of t...

Problems solved by technology

[0003] The purpose of the present invention is to effectively solve the problem that the parts manufactured by the current additive manufacturing equipment are difficult to be directly used in actual production. It provides a parallel additive and subtractive composite manufacturing machine tool, which integrates the additive manufacturing module and the subtractive manufacturing module. On the parallel mechanism, the alternation of additive manufacturing and subtractive manufacturing is carried out according to the CAD model data. Using the characteristics of no cumulative error and high precision of the parallel mechanism, the one-time molding and manufacturing of complex curved surface parts is performed without secondary processing and replacement. The knife manipulator can realize the automatic replacement of the functions of the additive manufacturing module and the subtractive manufacturing module, which can effectively improve the processing efficiency and forming accuracy of complex parts
