How to understand Lead Chart and Profile Chart in Helical Gear Drawing?
See Below Pics. Some Information of the Helical Gear:
PROFILE TOLERANCE (SEE FIG. 1) 0.0038
LEAD TOLERANCE (SEE FIG.2) .01
A call-out note for two holes on a casting drawing say:
?.468 Drill
?.500 Reground E.M.
?0.5025 Reamer
2X?.5025+/-0.010 THRU
questions:
1. what's E.M. represent?
2. Reground is supposed to have a higher accuracy than "Reamer", why is the "reground" before "Reamer"?
3. Is "Reground"...
