“…Figure 10 demonstrates the load-deflection curves from the experiment, FEA, and two theoretical equations from Almen and László's and Curti and Orlando's work. The difference in load at 0.25 mm This finding is identical to other reports [7,8], which lends confidence to the reliability of the current FEA model.…”

In a high-speed gas spindle, the drawbar force required to hold the drill bit is produced by the deformation of disc spring stacks. This drawbar force, applied to the collet-spindle interface, generates a contact pressure on the collet to hold the drill bit in position. Thus, the behaviour of the collet-spindle interface is critical to machining quality. Accordingly, this study investigated how disc spring characteristics affect the collet-spindle interface in a high-speed spindle. Typically, the drawbar force will decrease following the deformation of disc springs resulting from the effects of centrifugal force at high rotational speeds. This effect must be considered, especially in high-speed spindle applications. This study first measured the drawbar force experimentally and compared these results with theoretical and finite-element analysis (FEA) data under static conditions (i.e. no rotation). Having obtained satisfactory agreement among these data, the FEA was extended to a further investigation. Properties of the collet-spindle contact interface were analysed, given changes in rotational speed from 0 to 300 000 r/min under various disc spring deflections, various friction coefficients between the disc springs and their support, and distinct taper angles at the collet-spindle interface. All of these conditions are discussed here. These essential parameters are believed to cover much of the design of high-speed gas spindle systems.

A slotted disc spring consists of two segments: a coned disc segment and a number of lever arm segments. In this study, a load-displacement formula for the slotted disc spring is newly developed in the form of energy method by considering both rigid and bending deflections of the two segments. This formula is developed with the aim to further improve the SAE formula which is limited to a straight slotted disc spring. The coned and the lever arm angles of the straight slotted disc spring are the same. They are different for a bended slotted disc spring. Because of this limitation, it is geometrically impractical to employ the SAE formula for a bended slotted disc spring. To achieve the goal of this study, new calculations based on geometric and material properties inputs are developed for a bended slotted disc spring. A firm background study based on the theory of Almen is presented in developing new load-displacement calculations for a bended slotted disc spring.
