| 中文摘要: |
| 目的 促进钛合金精密铸造在设计和生产中，合理使用航标(HB 6103—2004)表达铸件尺寸。方法 对国内钛合金精密铸造产品在尺寸检测时遇到的问题进行分析，通过总结实际案例简述仅使用HB 6103对铸件进行尺寸测量时造成的影响。结果 HB 6103是行业内对铸造尺寸公差的规定，其基本尺寸（独立尺寸）公差分为16级。铸件在图纸尺寸的标注上应配合使用尺寸公差和几何公差，单独使用尺寸公差会导致产品尺寸信息表达不全，难以精确传达设计者的初始意图。结论 设计者应根据产品实际使用工况合理使用航标HB 6103中的铸造尺寸公差，完整、合理地表达铸件尺寸，有助于提高图纸的可读性，同时有助于提高铸件尺寸的合格率。 |
| 英文摘要: |
| The paper aims to promote the precision of titanium alloy casting during design and production, and express the dimensions of casting correctly with navigation marks (HB 6103—2004). Issues in precision casting of titanium alloy product in China were analyzed. Influences of dimensional measurement of castings only with HB 6103 were summed with actual cases. HB 6103—2004 was the standard of tolerance for casting in the industry. Its basic size (independent dimension) was divided into 16 grades. The dimension tolerance and geometric tolerance should be used in the dimension of the drawing. And the exclusive use of dimensional tolerances will lead to failure of expressing all information on product size, and thus affect the product quality. The designer should express casting size reasonably with the dimensional tolerance of casting in dimensional tolerance HB 6103 based on actual production use and working condition. It will be helpful to improve the readability of drawing and the yield of high casting size. |
