: i have a shaft on which three holes equispaced at 120 deg angles and p.c.d is 26 mm. Tap size is M6 x 1 mm thread forming operation. Center locating dia is 10 +/- 0.025 and MMC given is 0.50 max. for each hole how to calculate the p.c.d gauge size and its pin sizes to accomodate the 0.50 position tolerance. please suggest me with supporting formulas and documents. and what is the perpendicularity .

: thanks
: regards
