Taper Calculator Hard Key
Calculate tapers either by entering dimensions from a print, or by
touching a tapered workpiece with a tool, or indicator.
Use the taper calculator to calculate taper angle.
Entry values:
For the taper ratio, calculation requires:
 Change in the radius of the taper
 Length of the taper
For taper calculations using both diameters (D1, D2), and length
requires:
 Starting diameter
 End diameter
 Length of the taper
Press the CALC hard key.
The soft key selection has now changed, and includes
the taper calculator functions.
To calculate the taper angle using two diameters, and
length between, press the TAPER: D1/D2/L soft keys.
First taper point, DIAMETER 1, either enter a point
using the numeric keys, and press Enter, or touch the
tool to one point, and press NOTE.
Repeat this for the DIAMETER 2 field.
When using the NOTE key, the taper angle is
automatically calculated.
When entering data numerically, enter data into the
LENGTH field, and press Enter. The taper angle will
appear in the ANGLE field
To calculate angles using the ratio of the diameter
change to length, press the TAPER: RATIO soft key.
Using the numeric keys, enter data into the ENTRY 1,
and ENTRY 2 fields. Press Enter after each selection.
The calculated ratio, and the angle will appear in their
respective fields.
