Angular spindle. Calculation of the dimensions using a dial
indicator.
This example calculates the dimensions of a YZ 45º angular spindle (same as in the previous
example), parameter TYPE = 6. The next example uses a dial indicator and a cylinder of
known diameter placed in the spindle.

How to use the dial indicator.
When touching a cylinder with a dial indicator, contact must be made on the outside line of
the cylinder. Otherwise, there will be a measuring error when presetting the value of the
cylinder value. The dial indicator should be as perpendicular as possible to the tangent of
the surface being measured.
A simple method to place the dial indicator on the most external line of the cylinder is to move
the dial indicator on the circumference of the cylinder. To do that, preset ·0· on the axis to
be moved. When moving the axis, the needle of the dial indicator will rotate in one direction
and after passing the most external point of the cylinder, the needle will rotate in the opposite
direction. Continue with the movement until the needle of the dial indicator reaches its initial
value. The most external point will be in the middle of the distance traveled by the axis.
