Article Preview

Production of high precision circular scales is a complicated process requiring expensive equipment and complex processes to achieve. Precision angle measurement equipment tends to be very expensive and therefore not accessible to all in need. Simplification of production of such devices can lead to reducing costs of angle measurement systems ensuring easier accessibility. A new method of producing precision circular scales using low cost mass production can reduce the costs of these devices drastically. Therefore, utilising a common CD technology as the basis for such scales is analysed. This paper deals with the analysis of the newest laser cutting method for plastic circular scales. Preliminary results of manufacturing such scales are presented in the paper as well as measurements of the grating of the scale were performed. The quality of different scales manufactured using different laser types is analysed in the study. The cost – effective alternative of manufacturing circular scales is discussed in the paper.
