The specular surface of mold die etc were not obtained suitable diffuse reflection for non-contact CMM used laser probe, therefore the surfaces were treated white powder sprayed in order to change for generated diffuse reflection surface. Measurement error of non-contact CMM was increased that ups and downs of surface was formed by human skill white powder sprayed as serious influence, therefore the experiment was studied to extract significant factor for the automation of white powder sprayed work. As a result, it could be extracted significant factor for example sprayed method etc.
