Stylus profilometer gauge calibration, which often involves complicated procedures and demands expensive calibration standards, is substantial for ensuring both repeatability and reliability of surface roughness measurement results. However, in spite of numerous calibration methods being proposed, not only has the problem remained unsolved, but it even arose as incredibly wide range stylus profilometers came into the market recently. In the paper, a novel method is proposed in order to simplify the calibration process and interpretation of its results without decline in accuracy. The main idea is to replace the costly standards dedicated to profilometers with a sine bar and gage blocks, which are a must-be in every metrology laboratory. As a result, a calibration of these high-accuracy measuring instruments becomes fast and inexpensive. Moreover, this time and cost efficiency corresponds with the intuitiveness and easiness of interpreting calibration outcomes. In the paper, the core principles of the method are outlined and some experimental results demonstrating its performance are presented.
