Question: A two-axis NC system is used to control a machine tool table uses a bit storage capacity of 16 bits in its control memory for each axis. The range of the x-axis is 600 mm and the range of the y-axis is 500 mm. The mechanical accuracy of the machine table can be represented by a normal distribution with standard deviation = 0.002 mm for both axes. For each axis of the NC system. determine
(a) the control resolution,
(b) the accuracy, and
(c) the repeatability.
