Serrating On The Lathe Production Machining

The process continues until the part indexes full-circle and the serrations are completely formed. The procedure is both easy and fast. For example, the serrating of a part made of 1045 steel can be achieved on a conventional CNC lathe with C-axis capability in as little as 7 seconds. Incorporating the serrating operation as a lathe operationThe aerodynamic coefficients for the clean configuration of the ADO30 airfoil at R e c = 3 ⋅ 10 6 have been measured and presented in Fig. 4 for different serration flap angles. From analysis of the lift curves, the trailing-edge serrations are found to behave as a flap of a reduced serration length [12], causing a significant increment of lift in the range Trailing-edge serrations effect on the performance of a wind
