Technological Assurance of Complex Parts Manufacturing

Abstract

The ways of intensification of machining complex parts of vehicles on the modern metal-cutting equipment were described. The classification of parts such as levers was developed on the basis of design and technological features. Based on the developed classification the structural code that allows to encode any lever design was proposed. The structural code can be used in computer-aided fixture design and in information retrieval systems for selecting optimal fixture for levers. The reasonability of intensification of parts machining such as levers was substantiated, the typical manufacturing process was analyzed, and opportunities for optimization subject to current trends in machining and technological capabilities of modern equipment were identified. The adjustable locating-and-clamping module characterized by high level of flexibility was proposed for CNC multiaxis machining operation. Comparative analysis of manufacturing processes by labor content, quantity of fixtures and machine tools, number of setups, and production area was performed.
