pub fn fit_tolerance_m(room_m: f64) -> f64Expand description
How far an internal part may reach past the room in its parent and still be a fit, m: the
coarse general tolerance (COARSE_GENERAL_TOLERANCE_M) of the room’s diameter. A part
drawn that much wider than a bore of that size, both made to the tolerance, can be made as a
fit: the bore at +t and the part at −t close a diametral interference of 2t, a radial one
of t. 0.5 mm for a bore of 6 to 30 mm, 0.8 mm for 30 to 120 mm, 1.2 mm for 120 to 400 mm;
none below 0.5 mm, and 4 mm past 4 m.
