Abstract:

This study is to quantify, if possible, the hazardous effects of the machining variables. Initiation of an explosive is a thermal phenomena where input energy, regardless of its form impact, shock, etc., is converted to heat, increasing internal energy until an activation level is reached - an exothermic chemical reaction occurs providing heat for additional reactions to occur, continuing the cycle, until a runaway condition exists. Therefore, if the effect of a machining variable is to raise explosive temperature, then it has increased the possibility for initiation to occur. Consequently, it was decided that an investigation of the heat producing effects of the machining variables, as manifested by explosive temperature increases, would provide the most beneficial insight as to their hazard-producing potentials.
