Additive Manufacturing (AM) can produce complex metal parts in low volumes. Unfortunately, AM inherently produces a stepped surface finish and metal parts produced by powder bed fusion processes can also have a granular texture. Parts are generally shot blasted to mask the effect of the stepped surface. Machining is only used in localised areas, due to the cost and difficulty in accessing complex part geometry. Automated abrasive finishing methods have shown significant promise but these offer poor control of part accuracy and in some cases can also be expensive/slow to apply. In the IMPULSE project a rapid automated finishing process, giving precise control of material removal, will be developed. This novel approach is based on robotically controlled non-contact methods using laser “polishing” and electrochemical machining. Using two complementary methods will provide maximum flexibility in terms of materials, part geometry and final surface finish

增材制造 (AM) 可以小批量生产复杂的金属零件，但增材制造本质上会产生阶梯状表面光洁度，而通过粉末床熔合工艺生产的金属零件也可能具有颗粒状纹理。由于复杂零件几何形状的成本和困难，阶梯表面加工仅用于局部区域，自动磨料精加工方法已显示出巨大的前景，但这些方法对零件精度的控制很差，并且在某些情况下也可能很昂贵/很慢。在 IMPULSE 项目中，将开发一种快速自动化精加工工艺，可精确控制材料去除，这种新颖的方法基于使用激光“抛光”和电化学加工的机器人控制非接触方法。在材料、零件几何形状和最终表面光洁度方面具有最大的灵活性
