Manufacturing Technology - Lab Report Example The first order of business was to machine the chamfer. The chamfer was created using a High Speed Steel (HSS) tool through tapered turning using the taper turning attachment. The tapering operation was measured for consistency to ensure that the angle or the dimensions were not exceeded beyond the drawing recommended levels. Next, the portion of the job, with the largest diameter was held inside the chuck. The next operation was to rough up the stock billet using the single point tool along with acceptable feed rates and depths of cut. The cutting speed for aluminum is recommended as 75-105 meters per minute (Smith & Peterson, 2008). The rotational speed of the lathe chuck was determined using the formula shown below: In a similar manner, the feed rate was required for determining how fast the piece would be fed to the lathe machine. Two different feed rates were used, one for roughing operations and one for finishing operations (Fox Valley Tech, 2014). The chosen feed rate for roughing was 0.65 mm per minute while the finishing rate chosen was 0.20 mm per minute. The entire stock billet was roughed out in the first series of operations, after which it was measured to determine how much finishing would be required. The finishing operations were carried out to create a stepped piece which would further require an external grooving operation and a chamfering operation on one end. The next operation was creating an external groove. This groove was created using a finer finishing tool with a much slower cutting speed and feed rate to contain accuracy. Once the external groove was machined into place, and measured for consistency at four different points on the circumferential surfaces of the groove, the piece was faced to size. The facing was carried out with the same finishing tool. The final step was to create a M8 thread on the 8mm diameter portion of the job. The piece was centered
