Abstract

The invention discloses a method for determining time of tool changing based on dynamic reliability. The method comprises the following steps: firstly, building a dynamic reliability model of the whole process flow; then, calculating the reliability of a tool according to the built model, comparing the reliability of the tool with an allowable reliability value, and determining the time of tool changing. As the method builds the dynamic reliability model of the whole process flow, the calculation formula of failure rate of the tool in each procedure is derived, the replaced tool is determined by taking the failure rate of the tool as a criterion, finally the maximum application of the tool is realized, and the cost is saved.

Description

technical field

[0001] The invention belongs to the technical field of mechanical processing, and relates to a method for determining tool change time, in particular to a method for determining tool change time based on dynamic reliability. Background technique

[0002] In modern society, high-precision automation technology has been widely used, and the machinery industry has put forward higher requirements for the reliability of the entire process of the product. It is closely related to the reliability of machine tools, operators, and tools. Therefore, it is necessary to study the reliability and sensitivity of tools. very important. If the reliability of the tool is poor, it will cause frequent tool changes, increase the product failure rate, and consume more man-hours and economic costs.

[0003] Ramalingam and Watson conducted research on the reliability of cutting tools, and established a probability model to determine the durability of cutting tools. K.-S.Wang et a...
