The results show that : the whole bit wear process can be divided into three phases ; the regularity of the machining time per hole with the number of holes machined is close to a periodic variation ; higher machining efficiency or working life can be obtained when the drilling pressure and the wall thickness of the bit are advisable 發現鉆頭的整個磨損過程可分為3個階段;孔加工時間隨孔數近似呈周期性變化;鉆壓和鉆頭壁厚適當時,可獲得更高的加工效率或者工具壽命。

A procedure causing a system , process , or operation to take on its most desirable configuration or procedures in the best or most efficient way ; for example , when arranging instructions and data in storage so that a minimum of machine time or space is used for storing or accessing them 使一個系統、一個過程或一個操作能取其最希望的結構的方法,或以最好、最有效的方式進行所采取的一些措施。例如,在存儲器中合理安排指令和數據的存放位置以便存入和訪問時花費的機器時間或空間最小。

Then , considering the practical production , machining time and set up time are detached , a novel scheduling algorithm with multiple process plans and set up time is addressed , and the result shows the proposed algorithm is well which is compared with no set time scheduling algorithm 在此基礎之上,結合實際生產,區分了工件輔助加工時間和加工時間,給出了有輔助加工時間的多工藝加工計劃調度算法,通過與前一算法的比較,證明了該算法的優越性。

Adopting the principle of parallel operation , the machining of workpieces coincides with the clamping and the materials circulation coincides with dislocation , and therefore , the complete machining time is reduced and the producing efficiency is the highest 采用平行作業原理零件加工與裝夾重合,物流與轉位重合,從而使整個加工節拍縮短,生產效率最高。

Equipment condition monitoring , pre - diagnosis , life evaluation , re - modeling scheduling and process track for reducing or eliminating stopping machine time is the base of intelligent electronic maintenance 設備狀態監測、預診斷、壽命評估、重新建模調度和過程跟蹤,以減少或消除停機時間,是智能電子維護的基礎。

In fact , the speed of programs is only very seldom limited by the amount of machine time they can get ( there are a few exceptions to this rule , such as sound or 3 - d graphics generation ) 事實上,一個運行著的程序對于它們的時間片只受非常小的限制(但是有一個非常小的例外,比如一些聲音或者3d圖象程序) 。

But it also meant that the chips needed more machine time to execute , making it impossible for the 801 team to achieve their performance goals 但是另外一個事實是芯片執行指令時需要更多的機器時間,這使得801項目組無法實現自己的性能指標。

Furthermore , grp wined system can not adjustment continuously and therefore affect the technics of production due to the limitation of machine timing 而且,由于機械調速的限制,導致纏繞系統的速比不能連續可調,影響了產品的工藝。

The model is tested by a typical die - cavity roughing , and shortening machining time and balancing cutting - load can be attained 通過典型模具型腔的粗加工試驗驗證,證明該進給率優化策略不僅可以縮短加工時間,而且可以使加工載荷均勻。

Rule of economy : programmer time is expensive ; conserve it in preferenc to machine time 經濟性準則:如果和機器時間比較,程序員的時間是昂貴的。

Rule of economy : programmer time is expensive ; conserve it in divferenc to machine time 經濟性準則:如果和機器時間比較,程序員的時間是昂貴的。

Rule of economy : programmer time is expensive ; conserve it in preference to machine time 經濟原則:寧花機器一分,不花程序員一秒。

Basic machine time 基本計算機時間

Available machine time 機器可用時間

It will save considerable machining time to use more than one tool in one machine to perform several machine operations either in sequence or simultaneously . 在一臺機器上使用數種刀具來順次或同時進行幾項機器操作,將節省大量加工時間。
