摘要:为建立多品种小批量产品检验工时数学模型,以现场数控零件检验标准化作业现状为切入点,绘制鱼骨图,从人、机、料、法、环几个方面分析,找出影响检验工时的因素有产品尺寸数、高精度尺寸数、产品类别、产品难度、检验工技能、使用量具个数。制定数据收集计划,为确定梳理出来的影响因子与检验作业时间是否是相互依赖的定量关系,对参数进行回归分析,确定众多参数中影响检验作业时间的真实参数和其主要供献率,最后建立检验工时数学模型。通过工程验证,用建立的数学模型测算检验工时具有比较快捷,且有可以定量、准确的特点。

Abstract:In order to establish the mathematical model of inspection man hours for multiple specification and small batch products, a fishbone diagram is drawn based on the current situation of on-site NC parts inspection standardization operation. The analysis is conducted from the aspects of human, machine, material, method and environment, and it is found out the factors which affect the inspection time are the number of product size and high-precision size, product category, product difficulty, inspection skill and the number of measuring tools. In order to determine whether the influence factors sorted out and the inspection man-hour are in interdependent quantitative relationship, the regression analysis is carried out on the parameters to determine the real parameters and the main contribution rate that affect the inspection man-hours. Finally, the mathematical model of inspection man hours is established. And the engineering verification shows that the established mathematical model is fast, quantitative and accurate for inspection man-hour measurement.
