Calculate the tonnage capacity of the broaching machine required to broach on the hole under the following conditions.
Diameter of the finished hole = 75mm, rise per tooth = 0.03mm
Tooth pitch = 10mm
Length of the broach = 750mm
Cutting speed = 6m/min, specific cutting pressure = 1300 x t0.4 N/mm2
(Where t is the uncut chip thickness)
If the tool and work handling time is 0.5min, estimate the production rate per hour
