Four Function Arithmetic
The four arithmetic keys,
+ - X /
, are available when you are in any
numeric entry field, such as X, Y, CENTER , or RADIUS . Just use these keys as you
would any calculator.
+ 2 5
ENTER
2 2 + 5 7
KEY
RESULT
The keys will act on a number that is already in the field. For example, if you move to a
radius field which already has a value of
3.125 , and you want to double it, just press:
2 ENTER X
to get 6.250 .
When you have more than one calculation in a field, the calculator will perform
multiplication and division before it does addition and subtraction. This means that you
can enter
3 + 1 / 8 to get three and one-eighth (the 1 / 8 is done before the 3 is added).
Trig and Math Functions
When you're entering data for a milling or positioning function, part dimensions will not
always be given. In some cases, it will be possible to calculate the dimensions using the
trig calculator. If the unknown coordinate can be expressed as a trig function, a square
root or the square of a number,
MILLPWR can calculate it.
While in a point entry field such as X , Y , or CENTER , press the CALC key. The following
trig function softkeys are shown.
Most of the calculator softkeys are divided in half. At first, the top half is “active”, while
the bottom half is “inactive”. Select the
SHIFT softkey and the bottom half of the
calculator options becomes active:
