F3 In EDIT and MDI modes the F3 key will copy the highlighted triangle/circular/milling/tapping value into
the data entry line at the bottom of the screen. This is useful when you want to use a solution developed for
a program input.
In the Calculator Help function, this button copies the value in the calculator window to the highlighted data
entry for Trig, Circular or Milling/Tapping calculations.
F4 In the Calculator Help function, this button uses the highlighted Trig, Circular or Milling/Tapping data value
to load, add, subtract, multiply, or divide with the calculator.
Trigonometry Help Function
The Trig Help page will help you solve a triangular problem. You enter the lengths and the angles of a triangle
and when enough data has been entered, the control will solve for the triangle and display the rest of the
values. Use the CURSOR up and down buttons to select the value to be entered with WRITE. For inputs that
have more than one solution, entering the last data value a second time will cause the next possible solution to
be displayed.
Circular Interpolation Help
The Circular Help page will help you solve a circle problem. You enter the center, radius, angles, start and end
points and when enough data has been entered, the control will solve for the circular motion and display the
rest of the values. Use the CURSOR up and down buttons to select the value to be entered with WRITE. In
addition, it will list the four ways that such a move could be programmed with a G02 or G03. Those four lines
can be selected using the CURSOR up or down buttons, and the F3 button will import the highlighted line into
a program you are editing.
For inputs that have more than one solution, entering the last data value a second time will cause the next
possible solution to be displayed. The CW/CCW entry is changed to the other value by pressing WRITE.
Milling/Tapping Help
The Milling/Tapping Help page will help you solve three equations relating to milling and tapping. They are:
1) SFM = (CUTTER DIAMETER IN.) * RPM * 3.14159 / 12
2) (CHIP LOAD IN.) = (FEED IN./MIN.) / RPM / #FLUTES
3) (FEED IN./MIN.) = RPM / (THREAD PITCH)
With all three equations, you may enter all but one of the values and the control will compute the remaining
value and display it. Note that the RPM value for equations 1 and 2 are the same entry.
When Metric units are selected, the units displayed change to millimeters, mm per minute, threads per mm,
and meters, respectively.
