“…However, the reliability of the tool magazine and ATC has not yet got a reasonable evaluation index. The mean tool change numbers between failure evaluation indices were proposed to calculate the mean time to repair and estimate the collected failure data of the chain-type tool magazine and ATC [96]. A method to study the reliability evaluation of the tool magazine and ACT was proposed by using the failure data of the circular tool magazine and automatic tool changer [97].…”

Numerical control (NC) machine tools are the fundamental equipment of the machinery industry. The reliability of NC machine tools directly influences the processing quality, productivity, and efficiency. This paper reviews the latest developments in the reliability analysis of NC machine tools. The main analysis methods and modeling techniques used in reliability assessment of NC machine tools are illustrated with brief case studies. The reliabilities of typical subsystems of NC machine tools are discussed. In addition, several important key problems and issues remain to be addressed about the reliability analysis of NC machine tools and opportunities for further research are identified.

“…Tool magazine and automatic tool changer (ATC) is one of the most important key function units of the tool reserving and exchanging in machining center, whose tool reserving capacity and tool changing performance directly affect the performance of the machining centers [1]. Based on the tool reserving capacity, shape and the way of tools changing, tool magazine can be divided into some types [2]. The disc-type tool magazine which shows disc shape is the one of them.…”

Double loop cutters arrangement can settle the contradiction between rotational inertia of the tool magazine and the dimension limitation of the cutter head effectively, and increase the store of tools. Disc type tool magazine with double loop cutters arrangement is designed and researched. The spring steel 65Mn is used to manufacture elastic cutter fixture as the holding device for its inner and outer loop tools. The dynamic deformation of elastic cutter fixture is discussed. The entire geometric movement process of elastic cutter fixture from being opened by the tool holder to accomplishing the whole action is analyzed. The effect and trend of inner stress caused by geometric deformation are studied. Furthermore, the force condition in each part of tool fixture can be calculated, thus predicting the motion stability and reliability of the elastic cutter fixture, and providing theory references for the design of elastic cutter fixture.
