Recent improvements in geometric modelling systems hove led to the need for more reliable end highly automated softwore for machine tool path generation. Current machining algorithms require that any port geometric information which cannot be determined from the modelling system be supplied by the user. Much geometric information Is needed i f the model used to represent the pert is incomplete....

The paper presents a new combination of two methods for tool path generation for five-axis machining proposed earlier by the authors. The first method is based on the grid generation technologies whereas the second method exploits the space-filling curve approach. Combination of the two techniques is superior with regard to the conventional methods and with regard to the case when the two metho...

Peacetime assault-related injuries amongst soldiers are common. Whilst the majority of incidents of assault do not result in permanent physical incapacity, some may be devastating, ruining careers and lives. Here we describe one such injury. There is no national register of such injuries; they may, therefore, be under-reported.
