Abstract:The ultra-precision master gears have important application in calibrating high precision gear measuring instruments or coordinate measuring machines and in military industry. Firstly based error interference of the angle-transferring curve, the periodical translocation technique (PTT) of gear-grinding to improve the indexing accuracy of ultra-precision gears is proposed. The conclusions are drawn by precision experiment: (1) controlling 2/3~3/4 of total teeth participating in regrinding process can obtain the smaller total cumulative pitch deviation; (2) with increasing of the number of teeth participating in regrinding processes, the effects on single pitch deviation is more obvious. Finally, the total pitch deviation Fp of the specimen reaches to 0.79   m (2.72), and the single pitch deviation fp reaches to 0.30   m (1.02) by adopting PTT technique and both of them reaches to submicron level.The precision gear-grinding experiments show the efficiency and practicability of the PTT technique. ?
