2. A rectangular plate 4X8 in. is in full contact with the base of a fixture. The hole in the workpiece has been machined to 1.500 in. at the exact center of the plate. Figure 2 shows this plate. The plug diameter is 1.495. Calculate: a) the maximum height of the plug if the 4-in. side is lifted of the plug, and b) the maximum height of the plug if the 8-in. side is lifted off the plug. c) Compare the two plug designs.

Question
Transcribed Image Text:2. A rectangular plate 4X8 in. is in full contact with the base of a
fixture. The hole in the workpiece has been machined to 1.500 in. at
the exact center of the plate. Figure 2 shows this plate. The plug
diameter is 1.495. Calculate:
a) the maximum height of the plug if the 4-in. side is lifted of the
plug, and
b) the maximum height of the plug if the 8-in. side is lifted off the
plug.
c) Compare the two plug designs.

d) Calculate the maximum
diameter of the plug for the 8-in. lift which will permit the use of a
0.250-in height plug.
e) Compare the clearance in part (d) with part (b).
f) If a chamfer height of 0.1 inch is added counter sunk in the hole,
what will be the plug height for cases a and b.
