Abstract
The article presents the researches of geometrical precision of silicone casting form manufactured with using of the process of rapid prototyping of the tools (RT – Rapid Tooling). The testing casting form is applied to the production of prototypes of sprockets with the polymer resins and also the casting waxes. The determining of real geometrical precision of silicone form in the relation to the theoretical assumptions determined on the basis of the parameters of the material card of applied silicone was the purpose of researches. Silicone form was created on the basis of the stereolitographic model of sprocket. The coordinates measurable machine WENZEL LH 87 was applied to researches. The measurements of form and also base model were executed in the scanning mode on the basis of model 3D-CAD of sprocket. In purpose of the acceleration of measurable process of base model, silicone form and also prototypes manufactured in form, the special program CNC was written. Program enables the executing of measurements in automatic mode. Measurements enabled determining of precision of manufacturing of form in the relation to nominal model 3D-CAD and also in the relation to stereolitographic base model. The next stage of the research works will concern of the execution of geometrical measurements of prototypes casted in silicone form with chosen materials: casting waxes, the polyester, the epoxy and polyurethane resins. Executed measurements will enable on determining of real precision of prototypes manufactured in silicone casting forms. The problems concerned of determining of geometrical precision of silicone forms and manufactured in them prototypes are considered seldom in the analysed literature from the range of rapid prototyping. From this reason presented researches in article create the original work in the theoretical and practical aspect.
