Abstract
Determination of spindle rotate speed of lathe is an important issue when machine tools with changeable spindle gear ratio cutting metal parts, especially in heavy load cutting. Genetic optimization is used to automate design in engineering application for minimizing volume or weight. A quantum genetic optimization method was applied to calculate rotate speed and ratio of spindle transmission for gain maximum motor efficiency in numerical control lathe. Quantum bit code way was applied to simplify calculation and improve compatibility. Rotate angle strategy gate were introduced to Quantum gate for realizing evolution operation. The results were compared with a trial and error procedure usually applied. Quantum genetic arithmetic produced quite well results promptly supplying economic cutting parameters of numerical control (NC) lathe.
