Tonnage: Use the following formula to calculate the tonnage required to punch a round hole in mild steel: Punch diameter x Material Thickness x 80 = Tons of pressure required. Example: to punch a 1/2" hole through 1/4" thick mild steel 0.500 x 0.250 x 80 = 10 tons required. Use the following formula to calculate the approximate tonnage required to punch a shaped hole in …

Milling operations of "steps": the narrower "slot" is 1.0" wide and, theoretically, could be machined with a 1.0" diameter tool; the preferred approach is to use a smaller diameter tool, so that the full width is achieved on the second pass. Use a 0.750" diameter end mill. The same tool can be used for the "wider" slot. Set-up:

Sometimes you can minimise the final thickness through the 'hinge' (connecting the burr to the parent workpiece) by using a slightly smaller slotting cutter (you can perhaps use an in between metric size) and then programming a cleanup cut to orbit round the slot, taking maybe 0.005 - 0.010" per orbit (the thicker the preexisting hinge, the more orbits it will take)

Broaching can be quite simple in geometry—cutting a keyway in a gear or other component, for example—or quite complex. Broaching is often used to cut precise diameters or to produce non-round holes in shapes such as a hex, square, or "double D.". You can also use broaching to cut splines, gear teeth and other shapes.

Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

Bending Brass Bar. For thicker brass bars, consider scoring the bar prior to bending it. By removing some of the metal on the inside of the bend, you create space for the metal to fold in on itself. The scored line also ensures that the metal will bend at the spot you intend. Use a permanent marker to draw a line where the score will be made.
