Explanation: limit system is a series of tolerances arranged to suit a specific range of size. by this, limits of size are selected and given to mating parts to ensure specific classes of fit.
Explanation: a special control shaft is used to check this where a right angled blade is provided at right angle to shaft diameter line. the ocular line is made to coincide with the blade and the column is titled, the shift in position of the ocular line is noted, this shift is the required error.
Explanation: the permissible error which is allowed in the entire range of column rotation is ± 5′. a clinometer is used to check this which is of 1′ least count. the clinometer is put over column top. given inclination is further checked with clinometer.
Explanation: combinations can be made by only three series of angle gauges. minutes series is with 1’, 3’, 9’, 27’ angle gauges.
Explanation: 16 or 13 gauges can be divided into 3 series i.e. degree, minutes and seconds (fraction of minute).
Explanation: angle gauges are about 3 inch (76.2 mm) long and 5/8 inch (15.87 mm) wide. and their faces are lapped within 0.0002 mm.
Explanation: master angle gauges are laboratory standard and most expensive of all. they measure the angle with an accuracy of
Explanation: the standard angles gauges have 5 gauges present in the first series. they consist of 1°, 3°, 9°, 27° and 41° gauges.
Explanation: two sets of angle gauges are available. one set with 16 gauges with an accuracy of 1’’ and one set with 13 gauges with 3’’.
Explanation: direct combination of angle gauges can be made up to angle 81o40.9’. for the larger angle, square block is used with angle gauges.
