Introduction to Milling : Milling machine is one of the important machining operations. In this operation the workpiece is fed against a rotating cylindrical tool.

Sand Casting

Sand casting is the most commonly used expendable mold process. In this process, sand is bound together (as detailed in Table 7.9) and shaped to conform to the negative impression of the desired component. Molten metal is then poured into the sand mold; upon solidification, the metal has the geometry of the desired component. Table 7.9.

Sand casting . Process and Products

The process starts with a pattern, which is a replica of the finished part, except that it is slightly larger to allow for metal shrinkage during solidification and cooling. Then, a flask is placed around the pattern and sand is packed. Next, pressure is applied to the sand to compact firmly against the face of the pattern.

Sand transport processes in the surf and swash zones

The aim of this thesis is therefore to examine the sand transport physics in the breaking and swash zones, through controlled experiments in a large-scale wave flume.
