2. Profile gauge - Wikipedia

   en.wikipedia.org/wiki/Profile_gauge

   A contour gauge set to the profile of a small pot A contour gauge. A profile gauge or contour gauge is a tool for recording the cross-sectional shape of a surface. Contour gauges consist of a set of steel or plastic pins that are set tightly against one another in a frame which keeps them in the same plane and parallel while allowing them to move independently, perpendicularly to the frame.

3. Optical comparator - Wikipedia

   en.wikipedia.org/wiki/Optical_comparator

   The profile projector is widely used for complex-shape stampings, gears, cams, threads and comparing the measured contour model.The profile projector is hence widely used in precision machinery manufacturing, including aviation, aerospace industry, watches and clocks, electronics, instrumentation industry, research institutes and detection metering stations at all levels, etc.

   Dial indicator, also known as a dial test indicator, dial gauge, or probe indicator an instrument used to accurately measure small linear distances. Feeler gauge: a simple tool used to measure gap widths. Gauge block, (also known as a gage block, Johansson gauge, slip gauge, or Jo block) a precision ground and lapped length measuring standard.

   feeler gauge: gap widths forward looking infrared (FLIR) detects infrared energy (heat)converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations. framing square: right angles in construction frequency counter: frequency of alternating current: fuel gauge ...

6. Lapping - Wikipedia

   en.wikipedia.org/wiki/Lapping

   The light bands display a contour map of the surface of the workpiece and can be readily interpreted for flatness. In the past the light source would have been provided by a helium -neon lamp or tube, using the neon 632.8 nm line, [ citation needed ] or mercury vapor green line but nowadays a more common source of monochromatic light is the low ...

7. Planimeter - Wikipedia

   en.wikipedia.org/wiki/Planimeter

   The images show the principles of a linear and a polar planimeter. The pointer M at one end of the planimeter follows the contour C of the surface S to be measured. For the linear planimeter the movement of the "elbow" E is restricted to the y-axis. For the polar planimeter the "elbow" is connected to an arm with its other endpoint O at a fixed ...

   en.wikipedia.org/wiki/English_wheel

   This may involve the use of template paper, section templates (made using paper or thin sheet metal), station bucks, formers, profile gauges, profile templates and of course an original panel. Quick-release levers, which enable the operator to drop the anvil wheel away from the upper wheel so the work piece can be removed and inserted quickly ...

9. Center gauge - Wikipedia

   en.wikipedia.org/wiki/Center_gauge

   Center gauges and fishtail gauges [1] are gauges used in lathe work for checking the angles when grinding the profiles of single-point screw-cutting tool bits and centers. In the image, the gauge on the left is called a fishtail gauge or center gauge , and the one on the right is another style of center gauge .
