Abstract: PURPOSE: A control method of a cam system for generation of NC(numerical control) code of spur gear is provided to reduce interval number and NC code length and therefore working time of the spur gear through optimization of interval length by maintaining error in all intervals into permissible error range using GSS(golden section search) method. CONSTITUTION: In a step(S1), tooth number, module, pressure angle, arbitrary permissible error are inputted by a console. In a step(S2), variable such as angle at pitch circle, basic circle, root circle radius and arbitrary point related to tooth configuration of the gear is produced. In a step(S3), interval variable is initialized with substitution of 1. In a step(S4), interval error between corresponding interval length and predetermined interval length is produced by using GSS method. In a step(S5), the step S4 is repeated if the produced error length is larger than permissible error, and, if not, corresponding interval length is stored with adding of 1 to interval variable. In a step(S6), the step S4 is repeated if interval length corresponding to interval variable added with 1 is larger than 1 micrometer, and if not, length of last interval is stored. In a step(S7), NC code is generated according to position of a point between intervals.
