angle of cutting edge-
Second, the uncertainty of the relation between education and employment can be represented by some criteria such as graduates " employment rate, educational benefit dispersion grade, and the level of overeducation occurrence rate. third, personal choice, school, work - force market and work place are significant factors that affect the uncertainty of the relation between education and employment. fourth, in a society of market economy, the uncertainty of the relation between education and employment is a " sword with double blades ", thus it is necessary to avoid the disadvantages of the uncertainty of the relation between education and employment from the perspective of institutional layout
教育規模擴展和市場機制的共同作用，使得教育與就業之間也存在著不確定性； （ 2 ）教育與就業關系的不確定性可以通過畢業生就業率高低、教育收益離散程度、教育過度發生率高低等指標來進行表徵； （ 3 ）個人選擇、學校、勞動力市場和工作場合是影響教育與就業關系不確定性形成的重要因素，貫穿在教育與就業發生關系的全過程； （ 4 ）在市場經濟社會，教育與就業關系的不確定性是一把「雙刃劍」 ，因此有必要著重從制度設計的角度，對教育與就業關系的不確定性進行規避； （ 5 ）當前我國教育與就業關系的不確定性也開始顯現。From the political and military renewal of dynasties in history, in the later time of the communication period of two dynasties, the former dynasty ' s weapon captured would be used mostly, but at that time it ' s useless to use the former dynasty ' s weapon matched with the latter dynasty ' s fittings. once it were, it ' s rare, and it ' s impossible to be matched with the fittings over two dynasties
從歷史朝代更新變換的政治和軍事角度來看，兩個朝代的交接期，后朝多會直接使用繳獲的部分前朝武備，但用前朝的兵刃重配后朝的裝具在當時緊張戰局下純屬多此一舉，有也應是極少現象，隔代配裝更是不可能。Step 5 : at this point, you have successfully made the first zigzag pattern. just repeat the process until you reach your desired destination
第四步：保持你的角度垂直，前腳掌用力保持平衡。當你到達坡面的另外一個邊緣，移動重心和方向。重心逐漸壓向板頭方向，接著用前刃滑行。Which include cutting - edge curves, rake & flank face, edge angle, tool paths of enveloping rake & flank face, post processing technique of coordinate transfer, design - analyse and simulation sofeware. the research would offer sufficient academic basics and direction about manufacturing of ball - end cutters on the existing nc grinder
其中包括了球頭立銑刀的刃口曲線模型，前、后刀面模型，刀具角度分析，砂輪磨削前、后刀面的刀位軌跡模型，刀位軌跡與機床坐標轉換的後置處理，球頭立銑刀的設計與模擬軟體的開發。Secondly, based on cutting edge geometric model and machining mode of mk6335a grinder, the rake face with constant normal rake angle and flank face with constant orthogonal clearance angle models of ball - end cutters are discussed. the cutting geometry angle parameters are solved and analyzed. moreover, the tool paths models of wheel which grinding are builded and the post - processing technique for coordination transfer is studied
然後，基於刃口曲線模型、五軸數控磨床刃磨運動方式和微分幾何的直紋面概念，本文推導與建立了具有等法前角的前刀面和具有等主后角的后刀面的球頭立銑刀數學模型，並對球頭立銑刀的刀具角度如刃傾角、主前角、法后角、主偏角等參數進行了求解與分析。Good toughness and wear resistance, suitable for low speed cutting allowing a big rake angle, ensuring the sharpness of the edges, bearing a heavy cutting force and achieving good surface finish
具有優良的韌性和耐磨性，適用於低速切削，允許採用大前角，保證刀刃的鋒利性，從而可隨大的切削力，並獲得光潔度高的表面。分享友人
