Substrate Mastered Encoder Scale for Laser Cutting Machines

Download Whitepaper
Laser cutting is used across industries ranging from aerospace to civil construction. This article explores how Renishaw's substrate mastered linear encoder scales might be used in a fibre laser cutting application where a laser is used to precisely cut large sheets or plates of metal. A linear encoder consists of a position measurement readhead device paired with a scale (an accurately marked ruler). The readhead measures position by optically sensing the regularly-spaced scale markings and outputs this information as an analogue or digital signal. The signal is subsequently converted into a position reading by a digital readout (DRO) or motion controller.
