The Process Category Selection Model and Application of Silicon Rod Slicing Based on Green Manufacturing

The development of cutting technology of hard and brittle material went through cylindrical cutting and internal cutting,free mortar multi-line cutting and diamond multi-line cutting.At present the main processing method of solar grade silicon rod slicing is free mortar multi-line cutting and diamond multi-line cutting.The paper establishes a production target model for silicon rod slicing based on green manufacturing,cites 6 index of main parameters of free mortar multi-line cutting and diamond multi-line cutting for quality (Q), time (T), cost (C), environment protection (E), consumption of resources(R) and HMI properties(H) when cutting polycrystalline silicon 156.In order to select the best process category for silicon rod slicing based on green manufacturing,The paper attempts to study process category selection of Silicon Rod Slicing as a research object and adopts the analytic hierarchy process (AHP) and the fuzzy comprehensive evaluation method to calculate and assess.The results shows that diamond multiwire cutting is better than free mortar multi-line cutting on green manufacturing process planning.
