Abstract. Advances in CNC technology, coupled with improvements in computer systems provided the basis to review how computer-based systems can be used to allow universal fabrication. The G code no longer meets the current expectations of the program ever modern and complex machines. Indeed, the standard STEP-NC (STEP-Numerical Control) offers new solutions and integration of manufacturing in the full numerical chain. In this paper, we propose a new numerical control based on a standard high conceptual level STEP-NC machining process for prismatic parts, which aims to develop intelligent and powerful tools for sharing and data integration in CAD/CAM systems.

There is a growing need to automate the footwear industry by introducing new methods and tools to improve footwear production. The use of CAD tools for the design of shoes and their components is increasingly common, but it is a sector in permanent adaptation to socio-economic changes where it is therefore complicated to incorporate high-tech machinery. The introduction of improvements in production is a necessity, so the use of technologies that allow the adaptation of old machinery with the latest technologies in the area of CAD/CAM would be an important advantage for the sector.So far, each component is designed and manufactured separately. In this way, the real dependence that exists between the different components required for manufacturing footwear means that a change in any of these elements implies a redesign (CAD level) of the rest of the elements. This fact increases the manufacturing cost. It is also necessary to modify the way of manufacturing the product (CAM level), which is a complex manual process in many cases. The introduction of changes in an industrial environment with limited resources means a very slow implementation.In this paper, a platform based on STEP-NC is defined to show the advantages that its implementation in footwear sector would imply, by relating all the elements involved in footwear manufacturing: CAD tools that generate the geometries of the components, CAM tools that define the paths for their machining, and the different machines that manufacture these components. Furthermore, additional advantages would be incorporated, such as process control, supervision, inspection, allowing information to flow in all directions.
