*** 9760296 Taylor This Small Business Innovation Research (SBIR) Phase I project will explore a novel electrochemical process for final surface finishing of superalloys. Non-traditional machining technologies, such as electrochemical machining (ECM) and electric discharge machining (EDM) , provide near net shape machining of these and other difficult to machine materials or for applications with complex shapes, such as dies, molds, and aircraft parts. However, after ECM or EDM processes, time-consuming robotically controlled precision or manual polishing is required to do the final surface finish. Phase I will demonstrate a modulated reverse electric field process for final surface finishing. A model tool and die geometry, made from a commercially important superalloy, will be utilized to study electrochemical parameters critical to the quality of a finished surface. The electrochemical process is expected to achieve a surface finish less than 20 microns. Final finishing processes account for at least 25% of total processing time and in the case of manual finishing are operator specific. This novel process will find applications aerospace, automotive, die casting, and hot forging industries. ***

*** 9760296 Taylor 这个小型企业创新研究 (SBIR) 第一阶段项目将探索一种用于高温合金最终表面精加工的新型电化学工艺。 非传统加工技术，例如电化学加工 (ECM) 和放电加工 (EDM)，可以对这些材料和其他难以加工的材料或具有复杂形状的应用（例如冲模、模具和飞机零件）进行近净形状加工。 然而，在 ECM 或 EDM 工艺之后，需要耗时的机器人控制精度或手动抛光来完成最终的表面光洁度。 第一阶段将演示用于最终表面精加工的调制反向电场工艺。 由商业上重要的超级合金制成的模型工具和模具几何形状将用于研究对成品表面质量至关重要的电化学参数。 电化学工艺预计可实现小于 20 微米的表面光洁度。 最终精加工过程至少占总加工时间的 25%，并且在手动精加工的情况下是特定于操作员的。 这种新颖的工艺将应用于航空航天、汽车、压铸和热锻造行业。 ***
