Floating-point genetic algorithm (FAG)is used to calculate the three-dimensional space for workpiece of manufacturing system. Applying arithmetic crossover operators, the traditional GA mathematical model has been modified. This method has fast convergent speed. It is an effective method and its calculating precision is accurate. Its program used to C ++, and it can be realized easily using computer and CAPP. This method is the same with workpiece, which its data is discrete. It also measures workpiece of three-dimensional space for on-line product .It can find the global optimal solution. Finally, an instance is given that the process of internal spherical surface is more complex than other′s workpiece. It gets optimal solution of spherical radius and its tolerance.
