A model of a man-machine-environment complex is presented in which it is shown that each man-machine system defines for itself an operational environment from within the ecosphere. It is pointed out that this model has application to all design for human use, and to operation of man-machine systems. Its specific application to recreation is shown in relation to three areas—considerations of system safety in recreation; responsibilities and liabilities of manufacturers of recreational equipment; and responsibilities of researchers, human factors engineers, and those who supply manufacturers with operational design data. It is argued that safety management requires an epidemiological rather than a therapeutic or piecemeal approach, and that until safety is considered systematically as an objective in the design and operation of a man-machine-environment complex, recreational or otherwise, we cannot attain the optimal.

A generalized helical needle tip geometry model, which can describe many typical needle tip geometries, including conical, bevel, blunt and helical shapes with proper geometric parameters, is presented based on analogy to the helical point drill geometry. The generality of this model offers a general way for manufacturing various needle tip geometries. A mathematical model of the helical needle tip geometry is provided along with the formulation of the kinematic model of the tip grinding process. The control strategy on a 5-axis grinding machine system is also developed to implement the designed kinematic model. The needle tip’s motions in the grinding process are simulated to characterize the effects of grinding parameters on needle tip properties and to predict the trajectory of the needle tip point during the grinding process. Finally, several types of needle geometries have been manufactured by the developed grinding process to verify the newly formulated models.
