    The research project was developed due to mold manufacturing market demand for shoes soles. Since, one of the main problems is the lack of tools that cover Computerized Numerical Control (CNC) machining programs’ demand; which integrate advanced cutting strategies in their latest versions. This type of technology has evolved over time. In addition, market trends have required program developers to integrate functions that were not possible in the past. However, the best cutting strategies are not enough if resistant tools that have a durable design are not integrated. According to the presented study and through an experimental analysis, an adequate design of a rhomboidal counter-output tool is provided. Likewise, cutting parameters that guarantee a long life are established. The relevant factors in the experimental process are advanced speed and lateral pass depth. Since, machining advanced strategies appearance have been determined empirically. Consequently, material and time losses are generated during molds development. Trend continuous change of footwear models demands a flexible mold manufacturing process and implementation of adaptable machining tools. The proposal of this research includes a manual of sharpening procedure, according to proposed and validated design tool. Sharpening process is carried out by a tool development team at different clamping angles. In addition, the appropriate tool material was determined, which has flexibility to increase lateral pass value percentage.
