Measuring a taper / calculating an angle

On a taper, the angle 

α between its mean line and the base plate is to

be determined. It must be possible to laterally displace the workpiece

by a clearly defined amount. To do this, attach a stop to the base plate

and place a gage block between the stop and the workpiece.

A gage block is required, which is somewhat shorter in length than the

height of the taper.

For the measurement, a probing element with cylindrical styli is

necessary which must be aligned parallel to the base plate.

Procedure

–

Calibrate a cylindrical probe (standard or with a groove),

see chapter 2.1

–

Place the gage block between the workpiece and the stop and

position the probe above the narrow end of the taper.

–

–

Remove the gage block and slide the workpiece towards the stop

until it makes contact
