auto tool change cycle

Research on evaluating the tool changing time of ATC of machining center;

對加工中心自動換刀裝置換刀時間的探討

This paper firstly consider the Bertino’s work which introduce periodic time and temporal dependencies in DAC model, and then presents a permission delegation model PDACDM to support temporary constraints, temporal dependencies constraints and propagation constraints.

參考Bertino等人的工作,基于他們提出的加入了周期時間和時序依賴的自主訪問控制模型,給出了一個支持臨時性限制、時序依賴性限制和傳播性限制的權限委托模型PDACDM。

A weighted role for activating task and periodic time authorization is an unsolved major problem for the access control of a workflow management system (WfMS).

帶權角色激活任務和周期時間授權是工作流系統訪問控制研究尚未解決的核心問題。

The traditional RBAC model cannot express time secure access control constraint,so proposed a new RBAC model with time character,in which defined a new concept of authorization based on periodic time.

針對傳統的RBAC模型不能表達時間特性安全訪問控制約束的缺點,提出了一個帶有周期時間特性的安全訪問控制模型。

G eneva type, Arm type A. T. C. system with bi-direction and random tool selection function can minimize tool changing time, as well as enhancing the efficiency of machining.

斗笠式，刀臂式自動換刀系統可做雙向，最短距離選刀，大幅縮短換刀時間，提升加工效率。

Tools are changed in six seconds or less.

刀具能在六秒或吏短的時間內更換完畢。

In addition, they have minimized the time lost in changing tools, carrying out gauging operations, and aligning workpieces on the machine.

此外,更換刀具,測量和工件定位的時間也縮短至最低限度。
