Purpose: This paper propose a method to optimise the module of cutting conical spur gear, after being worn or broken, with the aid of Computer-Aided Design (CAD). The suggested method allows determining the geometric features of a pair of conical spur gear after worn. Design/methodology/approach: The approach consists of drawing real tooth model, with dimensioning characteristics by CAD; extracting a database of tooth drawing that permits the determination of the real volume by mass destruction. It also allows creating a virtual model, by theoretical geometric characteristics, to calculate the volume. Findings: This approach allows giving an approximation of the conditions of the machine function. However, the optimisation of the module is only a link one chain, for other parameter influences on the good working of pairs; we could mention the condition of assembly and the tribological aspects. Practical implications: A simulation package, R2000, was used and an ''AutoCAD'' software has been developed to accomplish the drawing of 2D wheel conical spur gear, the verification of the system assembly and the drawing of a 3D volume pattern. Originality/value: The numerical program gives, solution of optimization problem which consist of searching an extreme by minimising a constrained, unstrained function f(x) such that Min f(x) = -Max f(x).
