Development of the PKM-100 Сomparator
The design and peculiarities of the comparator PKM-100 pre-designated for measuring the median length and determining the deviation from the plane-parallel of the end reference plane-parallel measures of length 2, 3 and 4 bits and working accuracy classes 1-5 with a length of 0.1 to 100 mm. The design of the cassette for locating gage blocks from 0.5 to 100 mm and the measurement scheme on the PKM-100 comparator are described in detail. A special cassette based on a flat glass plate PI-60 was developed to base thin measures with a nominal length of 0.1 to 0.5 mm. in the second, there are channels for vacuum supply and reliable fixation of end measures with cross-sectional dimensions of 20 × 9 and 15 × 5 mm. Method and results of comparator verification confirming its technical characteristics are given, which allow to use comparator for verification of end measures of the second category.
