Abstract

This paper proposed the algorithm to select optimal grinding condition for plunge grinding in the batch production unit. In order to apply to the proposed algorithm, the state variable for plunge grinding process was defined and the optimal grinding condition for each cycle in batch production was decided by genetic algorithm. Based on the optimized grinding condition in each cycle, the optimal grinding condition for whole batch production was selected by dynamic programming. The proposed algorithm was evaluated by computer simulation.

본 논문에서는 배치 단위로 이루어지는 플런지연삭의 최적 연삭 조건 선정을 위한 알고리즘을 제안하였다. 제안된 알고리즘은 연삭공정을 나타내는 상태변수를 선정하고 선정된 상태 변수를 바탕으로 각 사이클에서 이루어지는 최적의 연삭 조건을 GA(Genetic Algorithm)를 이용하여 선정하였다. 이를 바탕으로 전체 배치 단위의 최적 연삭조건은 DP(Dynamic Programming)를 이용하여 구하였다. 제안된 알고리즘을 시뮬레이션을 통해 그 가능성을 검증하였다.
