Description of BS 3730-2:1982 1982This Part of this British Standard specifies the characteristics of contact (stylus) instruments based on the method of determining departures from roundness by measuring variations in radius. It relates to the assessment of the departures from ideal roundness of a workpiece through the medium of a profile transformation, obtained under reference conditions, expressed with respect to any one of the following centres:
Departures of roundness from the measured profile, use of instrument, calibration and determination of systematic errors of rotation are dealt with in Appendix A to Appendix D, respectively. Appendix F gives rules for plotting and reading polar graphs.
Characteristics of contact (stylus) instruments based on the method of determining departures from roundness by measuring variations in radius. Appendices deal with departure from roundness of the measured profile, use of instrument, calibration, determination of systematic errors, least square centre and circle plotting and reading polar graphs.
