Integration of CAD and rapid manufacturing for sand casting optimisation
In order to reduce the time and the costs of the products development in the sand casting process, the SMC Colombier Fontaine company has carried out a study based on a tooling manufacturing with a new rapid prototyping process. This evolution allowed the adequacy of the geometry used for the simulation to the tooling employed physically in the production. This allowed a reduction of the wall t...
متن کاملDesign, Manufacturing and Surface quality Analysis of Machining by Self-Rotary Milling Tool
One of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. As a result, the tool would be worn and its life time would be reduced. Therefore, in long time machining, it is essential to change inserts and tools, continiously. A milling tool with self rotary cutting inserts was designed and manufactured that enables i...
متن کاملThe Drying Kinetics of Protective Coatings Used on Sand Molds
Ł. Jamrozowicz, J. Zych, J. Kolczyk, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland Investigation results of the drying rate of the selected protective coatings (water and alcohol) are presented in the article. Coating drying rate was determined for the first and second layers. The coating was applied to moulding sand cores. The rate of drying coatings ...

متن کاملRapid Manufacturing of Co-Cr-Mo Implants by Three-Dimentional Printing Process for Orthopedic Applications
The fabrication of complex-shaped parts out of (wt %) Co-28Cr-6Mo alloy by three-dimensional printing (3DP) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. To produce sound specimens, 3DP processing parameters were tuned. The sintering behavior of the powders was characterized by the dilatometric analysis. Batch sintering in argon atmosphere at 1280 °...
