It has been a result of the increase in technology present in our society, which has emerged the need to control the information stop to make better decisions more quickly. In order to streamline and systematize the decisions to take it is necessary to provide a structure to the questions that have to be decided.
Planning process means the Act of preparing instructions for detailed operations to convert engineering design in a final piece. The appearance of the CAPP (Computer Aided Process Planning) systems dating from the beginning of the 1980s and they set off in order to bridge the gap between the CAD and CAM systems.
The objective of this paper is to create a low decision support system in CAPP approach that considers the technological variables (characterization of the pieces and the resource parameters) to determine the best routes in the process of stamping.
2 Experimental
((El_estudio_se_ha_estructurado_y_llevado_a_cabo_en_tres_partes:_a) specifications of the parts to stamping, b) analysis and study of the operations of stamping and c) characterization of resources to run operations
The concept of feature applied to a single stamping process to characterize each of the work carried out has failed to address the analysis of the parts to stamping. In the study of operations and their cataloguing has been possible to estimate the necessary time of manufacture. Finally, through the characterization of the resources it is feasible to evaluate different possible processes that can run for stamping a piece.
3. Results and discussion
4 Conclusions
The establishment of a framework decision has clear increased the time of determination of the alternatives of production and the tools to use for each resource. At the same time, the decision-making system has systematized by which thing is allowed to include experimentation with scheduling of processes within the environment of an information system.
