The accurate measurement of precision watch components places a number of special challenges on metrology systems used for inspection and process control. The small part sizes, variety of shapes, different gear geometries, and tight clearance specifications are all critical considerations when designing a metrology application for process control and inspection of watch components.
In addition, the range of materials and surface finishes used in watch components can inject an extra dimension of difficulty into the inspection process. To meet these challenges, metrology platforms must provide very consistent accuracy and repeatability with excellent autofocus capabilities and grid-focus options, plus a high degree of overall programming flexibility.
