22.1
When
a sine bar was in position to measure an angle, the gauge block stack height
was 1.99368 inches. What would be the angle if:
a)
a
5-inch sine bar were used?
b)
a
10-inch sine bar were used?
22.2
A
taper shaft similar to the one shown in Figure 22.6 was found to have dimension
H
2
= 8.326 inches and
H
1
= 6.168 inches. Calculate the
total included angle of the taper if a 10-inch sine bar was used.
22.3
A
toolmaker requires an angle of 39.636°
.
a)
Using a 5-inch sine plate, what
height
H
of gauge blocks is required?
b)
If
the stack of gauge blocks were used with a 10-inch sine plate, what would be
the angle measurement?
22.4
In
checking an angle on a machined casting, a 5-inch sine bar was used that had
buttons (rolls) fastened to the side. The lower button was 2.1672 inches above
the surface plate and the upper button was 4.8634 inches above the surface
plate. What is the angle measurement?
22.5
A
10-inch sine bar with buttons on the side has the following two measurements: lower,
5.6729 inches; upper, 9.2173 inches. What is the measure of the angle?
22.6
The
measurement to the buttons of a 10-inch sine bar from the flat were taken as
3.2763 inches and 8.4976 inches. What was the measure of the angle?
22.7
Determine
the stack height (gauge blocks to the upper button) of a 5-inch sine bar with
two buttons when the lower button is 0.7500 inch above the flat and the angle
is 22.373°.
22.8
Calculate
the stack height of gauge blocks to set a 10-inch sine plate to an angle of
37.175°.
22.9
The
stack height for a 10-inch sine plate used in measuring an angle is 3.5837
inches.
a)
What
is the angle measurement?
b)
If
a 5-inch sine plate were used on the same stack, what would be the angle
measurement?
22.10
A
10-inch sine bar with buttons is placed on a taper shaft whose included angle
of taper is 19.5°. If the short stack measures 1.350 inches, what is the height
of the upper button stack?
22.11
A
workpiece is placed on a simple sine plate as shown in Figure 22.7. Calculate
the stack height
H
of required
gauge blocks to raise the upper plate to an angle of 31.83° when
L =
1000 mm.

In
Figure 22.7, solve for
M
when
L =
127 mm,
H =
82.672 mm,
A =
28.575 mm, and
B =
30.162 mm. Give answer to 0.001
mm.
22.13
The
L
distance on a metric sine bar is
100 mm. Find the angle of a set-up when the gauge block stack equals 14.925 mm.
22.14
An angle of 47.66° is to be set up on a sine bar whose
L
dimension is 200 mm. Calculate
the stack height of the required gauge blocks.
