Relationship between Finishing Groove Design and Negative Allowance Control of Hot Rolled Ribbed Steel Bars 热轧带肋钢筋负公差控制与成品孔槽设计的关系
The Method of Finishing Exact Allowance to Assure Multiple Design Dimensions 用精确余量加工法保证多个设计尺寸
In order to determine the finishing allowance of double-circular-arc gears, the author recommends a procedure for measuring the base tangent length before finishing-cut and derives the relation between the finishing allowance and the base tangent length. 为确定双圆弧齿轮粗切后的精切余量,安排了精切前公法线长度测量工序,并推导了精切余量与公法线长度的关系式。
It introduces a half finishing methed for one axial structural size in order to control end finishing allowance and to assure many axial sizes to satisfy the drawing demands at the same time by one cut. 介绍了某一轴向结构尺寸采用半精加工和精加工,从而控制端面精磨余量,以保证一刀切削使多个轴向尺寸同时达到图纸要求。
