Entering formulas
You can enter mathematical formulas that include several
operations directly into the part program by soft key.
Press the
FORMULA soft key to call the mathematical functions.
The TNC displays the following soft keys in several soft-key rows:
Mathematical function Soft key
Addition
e.g. Q10 = Q1 + Q5
Subtraction
e.g. Q25 = Q7 – Q108
Multiplication
e.g. Q12 = 5 * Q5
Division
e.g. Q25 = Q1 / Q2
Open parentheses
e.g. Q12 = Q1 * (Q2 + Q3)
Close parentheses
e.g. Q12 = Q1 * (Q2 + Q3)
Square value
e.g. Q15 = SQ 5
Square root
e.g. Q22 = SQRT 25
Sine of an angle
e.g. Q44 = SIN 45
Cosine of an angle
e.g. Q45 = COS 45
Tangent of an angle
e.g. Q46 = TAN 45
Arc sine
Inverse function of the sine; determine the angle
from the ratio of the opposite side to the
hypotenuse
e.g.
Q10 = ASIN 0.75
Arc cosine
Inverse function of the cosine; determine the
angle
from the ratio of the adjacent side to the
hypotenuse
e.g.
Q11 = ACOS Q40
Arc tangent
Inverse function of the tangent; determine the
angle
from the ratio of the opposite side to the adjacent
side
e.g.
Q12 = ATAN Q50
