When machining helical gears, do they choose the cutter according to the end face modulus of the tool, or the cutter according to the normal modulus of the workpiece? Why?The report will be handed in tomorrow!
And these modules or a range of any value is possible. So, bring a lot of trouble to the manufacturing, and to use modules do not have this problem, as long as is the same to the spur gear modulus tool can be processed in any one of the helical gear and the modulus.
The gears with the same normal modulus, different helical angles will bring different normal modulus, that is to say, the same normal modulus of helical gear, there will be a lot of end face modulus,
Normal modulus, because the helical gear is from design to know, is based on modulus, because the end face modulus has a problem
