| Basic version: >0 cutting clearance is allowed without any support function. For support function, cutting clearance = 0 and helical grooves are used. 1) Cross-section usually depends on the profile of the seal. The value of the cutting clearance depends on the material and temperature. For details, please refer to the profile description. |
