Calculating and reviewing the profi le of an asymmetric involute tooth

The purpose of the spreadsheet is to generate the complete profile of the tooth of a cylindrical gear with straight teeth. The spreadsheet allows the dimensions of a cylindrical gear with asymmetric profile (where pressure angle and left hand base connection differ from pressure angle and right hand base connection) to be determined, and for any correction/shift between the pitch line of the hob and the pitch line of the wheel introduced during the cutting phase to be taken into account.
