Fig. 13From: Development of multi-pitch tool path in computer-controlled optical surfacing processesSimulation results of the 1# and 2# optic figures with (a) multi-pitch and (b) uniform pitch tool paths. PVe of S1 ~ S4 are all smaller than 0.01 λ, while PVe of V1, V2, V3, V4 are approximately 0.008, 0.02, 0.04, 0.06λBack to article page
