Abstract

See full text

A method for inspecting the influence of an installation environment upon a processing apparatus includes setting a mark for specifying a relative positional relation between a chuck table and a processing unit, imaging the mark plural times by using an imaging unit when a moving unit is at rest, and detecting the position of the mark from an image and then determining whether or not the influence of the installation environment upon the processing apparatus is present based on whether the change in position of the mark is less than or more than a threshold.
