How to calculate steel quantity for slab, footing, column

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.capability is shown in Table 1. The span capabilities of these precast concrete culvert shapes are based on 6.0 ksi compressive strength of concrete, and grade 60.0 ksi reinforcement.
