Equipment for Measuring Conical Parts

Tapered components play numerous roles in the devices we use daily and those that surround us, sometimes performing special or even indispensable functions. The aim of this paper is to design and implement a measuring device suitable for determining the taper and taper angle of pin-type tapered components. The basic concept of the measuring instrument is inspired by the sine ruler, while effective measurement is ensured by the displacement of a digital gauge along two perpendicular axes. The data processing is performed by an Arduino microcontroller, which displays the results on an LCD screen. We measured a workpiece with a known taper. The measurement accuracy was verified using hypothesis testing.
