| Summary: | The article discusses a method for automated measurement
of the length of the general normal of a helical cylindrical
wheel, which allows to obtain its exact value without
removing the part after gear processing with disk or end
mills. The measurements are carried out by means of an
automated supply of a three-coordinate linear measurement
indicator to the calculated measurement points. The
formulas for calculating the length of the general normal
are given, which allow calculating the value of the length
of the general normal and the correction value of the
CNC gear ring processing program for two and one-point
measurement schemes with the indicator. The use of the
two-point method of measuring the length of the general
normal with a three-coordinate indicator made it possible
to measure the length of the general normal without
removing the processed gear wheel from the mandrel, the
single-point method completely eliminates the possibility
of adjustment defects and reduces the complexity of
carrying out machine changeovers in the mode of single
and small-scale processing of gears. Comparison of gear
measurement data with the three-coordinate indicator
Mahr and a specialized CNC gear measuring machine
give similar values and confirm the possibility of using the
developed scheme to measure the length of the common
normal. |
