PURPOSE OF THE PROJECT
From
the research, it is expected that the student would be exposed to and
learn how to progress from design to actual fabrication of equipment,
using conventional system.
DESIGN AND OPERATION CONSIDERATIONS
In
general, to address the work holding needs of a particular machining
operation, one needs to consider part size, material, machine speed,
feed rate, and the quantity of Parts to be produced. Single part
production or low quantity requirements generally make a single vice
setup a good choice. The part configuration will point toward either
contoured jaws or any number of standard or special jaws. The gripping
area for the planned operation must allow for sufficient depth of jaw
engagement (bite) to safely allow the planned operation to take place.
Higher
quantity lot sizes make multiple vise setups desirable. The
workpiecesize determines the spacing between the vises as well as the
vise size itself. Generally, attempts must be made to produce the
maximum amount of parts per cycle. Many additional operations by the
same operator can then be done simultaneously. The key to freeing the
operator is quick clamping and the highest efficiency of the
workpieceloading cycle. This includes prepping the work area for
thorough chip flushing and cleaning.
But in particular, with reference to this project, the vise design is guided by the following considerations;
1. Adequate clamping forces
2. Quick and ease of clamping
3. Simple construction
4. Low cost
5. Durability
