报告针对X70连杆机加工艺的流程优化问题，通过借鉴成熟的流程方案和三维环境分析，对X70连杆加工工艺进行优化，主要措施：整合工序（将上下面精铣、铣4×45°倒角、铣R50等上下面上的特征在1个工序2个工位上完成、调整余量（大头孔直接粗铣到精镗孔前尺寸）、改变加工方式（R50圆角由镗改为使用R50球头铣刀、刀检R203由Φ63×160 调整为R50球头铣刀加工；并辅以随行工装，实现快速定位的装夹效果，完善作业指导书，使所生产的连杆能够满足图纸和技术文件的要求，该流程对今后其他类似连杆工艺具有借鉴意义。该报告还对未来的生产线进行了规划，随着后期设施逐步配套、进行合理组线，使其朝着自动化方向迈进。<br>该报告内容完整准确，符合撰写要求。经讨论，该报告通过评审。

The report focuses on the process optimization problem of X70 connecting rod machining process. By drawing on mature process plans and three-dimensional environmental analysis, the X70 connecting rod machining process is optimized. The main measures are to integrate the processes (including upper and lower precision milling, milling 4) × 45 ° chamfering, milling R50 and other features above and below are completed in one process and two workstations, with allowance adjustment (large head hole is directly roughly milled to the size before precision boring), processing method change (R50 fillet is changed from boring to using R50 ball end milling cutter, and tool inspection R203 is changed from Φ sixty-three × 160 adjusted to R50 ball end milling cutter processing; And accompanied by accompanying tooling, achieving fast positioning clamping effect, improving the work instructions, so that the produced connecting rods can meet the requirements of drawings and technical documents. This process has reference significance for other similar connecting rod processes in the future. The report also plans for the future production line, moving towards automation as the facilities are gradually matched and the production line is reasonably organized in the later stage.<br>The content of this report is complete and accurate, meeting the writing requirements. After discussion, the report passed the review.

Aiming at the process optimization of X70 connecting rod machining technology, the report optimizes the X70 connecting rod machining technology by drawing lessons from mature process scheme and three-dimensional environment analysis. The main measures are: integrating the working procedures (finishing the upper and lower features, milling 4× 45 chamfering, milling R50, etc. on two stations in one working procedure, adjusting the allowance (directly rough milling the big end hole to the size before fine boring), changing the machining method (changing the R50 fillet from boring to using R50) With the help of accompanying tooling, the clamping effect of rapid positioning is realized, and the work instruction is improved, so that the produced connecting rod can meet the requirements of drawings and technical documents. This process has reference significance for other similar connecting rod processes in the future. The report also made a plan for the future production line. With the gradual matching of facilities and reasonable assembly of lines in the later period, it will move towards automation.<br> The content of the report is complete and accurate, which meets the writing requirements. After discussion, the report passed the review.
