His father, Ilya Petrovich Tchaikovsky, had served as a lieutenant colonel and engineer in the Department of Mines, [3] and would manage the Kamsko-Votkinsk Ironworks. The semi-automated process provides a surface finish of 32 to 63 microns. Production: 5 to 12 weeks after approval. On most surface finish gage settings it is also known as Rq, which according to my info at hand is about 25% greater than Ra. Roughness, on the other hand, is the result of feed-rate tool geometry, tool condition, and variations in material and hardness. R max = Roughness maximum, measured in either Micro-inches or Micro-meters. 01 (C) Race points of corresponding competitors 99.
