Embodiment Construction
[0019] see figure 1 , shows an environment 10 for forming retroreflective prisms in a substrate that can be used to fabricate retroreflector molds and retroreflective sheeting using diamond microgouge. Diamond microchiseling (DMC) is a process in which a multi-axis high-precision machine tool cuts diamonds in and out through a substrate to remove material, such as "Diamond MicroChiseling of Large-Scale Retroreflective Arrays" by Brinksmeier et al. (Precision Engineering, 2012, p. 34, No. 4, pp. 650-57), the disclosure of which is hereby incorporated by reference in its entirety. DMC advantageously provides a method for producing retroreflector molds that include polygonal or other similarly shaped retroreflective prisms that cannot be produced using conventional fly-cut techniques. DMC also provides enhanced flexibility in retroreflector design. DMC allows the production of polygonal retroreflectors with increased effective area that meet various global specifications for su...
