High-speed electric machinery and tooth belt are adopted for doffer transmission, realizing stepless speed changing. 道夫傳動採用高速電機，齒形帶傳動，實現無級調速。
By way of a measuring face tageut with flauk profile andameasuring contact jigging along the tooth facem theminimundistance can be measured to show the batpitchdeviation. 利用一個與齒廓相切的測量面以及一沿齒面擺動的測量觸頭量得最小距離從而反映出基節偏差值。
The modifications of gear tooth profiles like tooth thickness, tooth tip and edge chamfers and root fillet radius are easily manipulated in a editing window. 如齒厚，齒尖和邊緣倒角及根圓角半徑齒輪齒廓的修改很容易操縱的編輯窗口。
