Give definition of material removal process

• A process in which a sharp cutting tool is used to cut away material to leave the desired part shape

• A process consists of a family of shaping, the common feature of which is that excess material is removed from a starting workpart so that the remaining part has the desired shape

• A process of converting raw materials into products including the design of the product, selection of raw materials and the sequence of processes through which the product will be manufactured

• A sequence of processes that add value to the material by changing its shape or properties, or by combining it with other materials that have been similarly altered.

The following are TRUE about machining

• Variety of work materials

  Variety of part shapes and geometric features

  Dimensional accuracy

The following statements describes the type of milling

• Direction of cutter motion is against the feed direction.

  The chip starts out very thin and increases in thickness during the sweep of the cutter

• Direction of cutter motion is against the feed direction.

  The chip starts out thick and reduces in thickness throughout the cut.

• Direction of cutter motion is against the feed direction.

  The cutter is engaged in the work for less time per volume of material cut.

• The chip starts out very thin and increases in thickness during the sweep of the cutter.

  The cutter is engaged in the work for less time per volume of material cut.
