Abstract
Multi-variety parts and small batch production are the main production characteristic of a certain company. How to improve the productivity even to reach a large batch size production is a critical project of this company. This article uses the group technology to divide the 124 parts into 9 groups based on the CNC manufacturing process and order quantity. Then we arranged the 9 groups on 11 different CNC machines. After such grouping, the productivity was increased 26%, and the production cost was reduced 20%.
