Abstract: This is directed to providing a cosmetic finish on a component constructed by connecting several elements. A single manufacturing process, such as machining or grinding, can be applied to the connected elements to remove material from some or all of the elements and to form a smooth and continuous surface across interfaces between the individual elements of the component. In some cases, settings of the material removal process can be adjusted based on the material of the component elements. For example, the settings can be adjusted based on the manufacturing or mechanical properties of each element material.
