• Description:
  Prolonged, intensive exposure to hand-transmitted vibration may occur among some workers performing handheld grinding of golf club heads. As a result, vibration-induced white finger (VWF) has been found among some of these workers. Some intervention is required to control this occupational disease. The objective of this study is to propose and discuss potential approaches for reducing the vibration exposure. Figure 1 shows an example of the fine grinding of golf club heads at a workplace. Our experimental study found that the golf club head vibration during its grinding process resulted from the vibration transmitted from the machine and that generated in the grinding process itself. Specifically, the majority of the large vibration peaks on the machines are in the critical middle frequency range (20 to 250 Hz). They are largely associated with the operation speed of the machine. This suggests that the machine vibration of major concern results primarily from mechanical sources such as unbalanced mass of the rotational parts, misalignments of shafts and bearings, tolerances in the bearings etc. The grinding vibration may result from the geometric irregularities of the grinding interface and the mechanical property irregularities of the grinding system. The dynamic responses of the club head and hand-arm system and the applied hand feed force may also influence the club head vibration. Based on these vibration sources, their characteristics, and the identified response mechanisms of the club heads, a set of potential approaches for controlling the vibration exposures to the grinding workers are proposed in this study.
