TASK 2
*Please use the following work procedure along with the machines’ safety and standard operation procedures.*
Milling process i)
Measure the initial thickness of workpiece and thickness to be removed from workpiece.
ii)
Clamp the workpiece on the vertical milling machine. Position of all parts of milling machine are as shown in the Figure 14.
iii) Adjust the position of milling cutter facing the upside surface of workpiece. iv) Set the depth of cut (z-axis) position for milling cutter following the thickness to be removed from workpiece. v)
Do the face milling process on the workpiece in a way of layer by layer of side material removal. Figure 15 illustrates the schematic diagram of how milling cutter cuts and removes the layer of workpiece material during milling operation.
vi) Repeat procedure (vi) to produce a workpiece with the dimension of 45 mm x 45 mm x 14.5 mm.
