Electrochemical machining (ECM) is applied to a wide variety of metal processing. While ECM has many machining characteristics, bubbles and electrolytic product disturb current flow and decrease the machining efficiency. To apply ECM to micro-shape machining, it is important to clarify the mechanisms of transitional and microscopic ECM processes. In this report, variations in the growth and diffusion of electrolytic product at each ECM power and at each electrolyte temperature were measured by a microscopic optical system and fast camera. The growth and diffusion of electrolytic product were investigated based on the experimental results. The relationship between machining characteristics such as machining speed and surface roughness, and thickness of electrolytic product that varied as the growth and diffusion conditions changed were experimentally investigated.

电化学加工（ECM）应用于多种金属加工。尽管ECM具有许多加工特性，但气泡和电解产物会干扰电流流动并降低加工效率。要将ECM应用于微观形状加工，弄清过渡和微观ECM过程的机理很重要。在此报告中，通过显微镜光学系统和快速相机测量了每种ECM功率和每种电解质温度下电解质产品的生长和扩散变化。根据实验结果研究了电解液的生长和扩散。加工速度和表面粗糙度等加工特性之间的关系，
