Introduces a flexible method of calculating that can magnify the too small tolerance and improve the economic benefit of machining parts through counterchanging the roles of close loop and component loop in dimension chain
為此，介紹一種變通演算法，變換尺寸鏈中封閉環和組成環的角色，將過小的公差放大，從而可提高零件加工的經濟性。 -
This interpolation module uses the popular and advanced nurbs interpolation technology. the procedures of math processing for nurbs, preprocessing for interpolation and real - time interpolating running on dsp are presented in this article. the interpolating procedure uses an advanced self - adjusting interpolation method, which can automatically adjust the length of interpolation according to machining speed, acceleration and the tolerance of bow height
插補模塊則採用了當今最流行最先進的nurbs插補技術，設計了nurbs數學處理程序，插補預處理程序，運行於dsp的實時插補程序，該插補軟體採用了先進的自適應插補方法，可以根據加工的速度，加速度，弓高誤差的要求自適應調整插補步長，同時採用了對插補點的預估演算法，免去以往加工方法中求導的運算，大大降低了運算量，提高了加工速度。 -
Machining allowance tolerance for rolled ring
