  3. 二.评定表面粗糙度的参数PARAMETER OFSURFACETEXTURE Yi Yn 请点击鼠标左键显示后面内容

  4. 二.评定表面粗糙度的参数PARAMETER OFSURFACETEXTURE Rz Rz 请点击鼠标左键显示后面内容

  5. 三.表面粗糙度符号SYMBOL OFSURFACE TEXTURE a:Ra的最大允许值,若写为a1/a2则为最大允许值/最小允许值; 若是Rz、Ry时应在数值前加写Rz或Ry,Ra字母可省,单位:m; b:加工方法代号(如:车、铣、镀涂或其它表面处理等); c:取样长度(单位:mm); d:加工纹路方向(如:M 等); e:加工余量(单位:mm); f:粗糙度间距参数值(单位:mm)或轮廓支承长度率。 请点击鼠标左键显示后面内容

  6. 四.表面粗糙度的标注LABELOFSURFACETEXTURE 若全部表面的粗糙 度相同,则可直接 在图的右上角注明。 国外图例 请点击鼠标左键显示后面内容

  7. 五.表面粗糙度的选用SELECTIONOFSURFACETEXTURE 请点击鼠标左键显示后面内容

  8. 六.练习题 Exercises 缺少其余“字样”,位置应放到图的右上方 粗糙度符号的尖端应与表面接触上 Ra应省略 12.5 12.5 (milled) 12.5 12.5 铣字应注在横线上 分界线应为细实线 粗糙度符号的长边画错 粗糙度符号的尖端应从材料外指向表面 练习1: 找出下图中粗糙度代号标注方法上的错误并改正之。 (milled) 请点击鼠标左键显示后面内容
