2. Shrinkage Calculations
SC-100 provides a very easy-to-use shrinkage function, and allows the operator to easily calculate the
expanded or reduced dimensions.
It is normally used in a case where incomplete shrinkage calculation have been made, ie some dimensions
have been forgotten to be marked onto the drawing. Using the SC-100 during the machining process, the
operator can calculate the shrinkage dimensions directly with the readout. SC-100 also provides an easy
method of verifying the calculated dimension marked on the drawings.
Example :
To calculate the shrinked dimension of 27mm
The current position of X axis is 123.45, therefore,
123.45 mm expands = 123.45 x 1.005 = 124.067
Calculation result will display in the message
window
27mm expand = 27 x 1.005 = 27.135
Calculation result will display in the
message window
Example :
To calculate the expanded dimension of
current X axis dimension
Example :
To calculate the expanded dimension of 27mm
27mm shrink = 27 / 1.005 = 26.866
Calculation result will display in the
message window
