Which instrument is employed for gauging gap clearance during preliminary alignment procedures?
Show answer Hide answer
Answer: A. Inside caliper
Explanation
Inside calipers are manual measuring tools used for checking internal dimensions. Machinists use them to gauge gap widths during preliminary mechanical setups. Measurements are then transferred to a precision rule for reading. Calipers provide comparative measurements rather than direct digital readouts. Alignment procedures require verifying clearances between adjacent machine parts. Manual skill is needed to achieve accurate tactile readings with calipers.
Machine alignment technicians use inside calipers during initial assembly stages. Workshop maintenance involves checking bearing housing clearances with calipers. Fabrication shops rely on basic hand tools for quick dimensional checks. Option B dial indicator provides high precision deflection measurements. Option C feeler gage measures tight gaps using calibrated steel blades. Option D measuring tape is used for rough linear distance measurements.
