A few modern industrial materials are of serious concern to the home model engineer turning with a light lathe machine. Virtually all turning is done using either carbon steel, high speed steel or tungsten carbide tipped tooling. This is mainly due to the fact that the newer and more exotic materials such as ceramic and diamond require high speed a...

Context 1
... small curve (crater) is also developed when chips pass along the tool surface, hence causing wear. Table 1 contains of data for speed, feed rate and depth of cut for medium to high speed steel taken from machine handbook by Jang et al. (1997). Most of the look-up tables give minimum and maximum roughness of the work piece but here it is not necessary because it is the controlled parameter and the roughness of the finished product is measured by the close match between the actual and the predicted model output. ...
Context 2
... indicated in Table 1, a data set comprising three sets of 24 data points divided into two halves was used. The first half was used to train the network and model was validated using the second half that the neuro-fuzzy had never seen. ...

Additive Manufacturing of Casting Die with Ideal Shapes of Gating System through Rapid Tooling
Conference Paper
Full-text available
  • Apr 2013
Producing tooling directly from CAD models to manufacture industrial products is regarded as an important method of reducing the cost and time to market the new products. A comprehensive review of examples of rapid tooling indicates a major shift in tooling practice. This paper describes the role of Additive Manufacturing (AM) technology in increasing the speed of tooling development. The proposed work presents a new design and manufacturing paradigm based on direct Rapid Tooling (RT) concept to increase casting yield by improving the geometry and design of gating elements which plays very important role in the production of sound casting. Ideal shapes of gating system (i.e. runner, riser and sprue) are obtained by using the additive manufacturing technique with help of solid based rapid prototyping machine. RT shortens the process by eliminating several steps of the cycle of traditional casting process and leads to design optimization. Casting yield and production time for unit product are the output parameters which are optimized by techniques of RT.
