Answer:
It means that a feature is dimensioned more than once.
For example, suppose you have a drawing of a rectangle, and the width is dimensioned twice. That's an example of over-dimensioning.
Of course, that's a rather obvious example. Sometimes it's more subtle. Suppose the rectangle has the width and height dimensioned, but also the diagonal. This is also an example of over-dimensioning. If the width and height are dimensioned, then you don't need to dimension the diagonal; that's already fixed by Pythagorean theorem.

Explanation:
The size needed to use the kerf on the laser properly is:
Answer:
Q = 8.845 DEGREE
Explanation:
given data:
combine Mass for 6 cylinder (M) =15 Kg/hr
mass of each cylinder (m) = 15/6 = 2.5 Kg/hr = 0.000694 Kg/ sec
Engine speed (N)= 1500rpm
Diameter of one nozzle hole ( d) = 200 micrometer = 0.0002 m
Discharge Coefficient (Cd) = 0.75
Pressure difference = 100 MPa
Density of fuel = 800 kg/m^3
velocity of fuel is
injected fuel volume (V) =Area of given Orifices × Fuel velocity × time of single injection × no of injection/sec
we know that p = m/ V
So
putting these value in volume equation and solve for Discharge
Q = 8.845 DEGREE
