HOMEWORK/TEST STUDY GUIDE MET 316

NAME:

The tools in Figure 1 have been touched off to the top surface of the part (using a 0.1” gauge block between the tool tip and the top surface of the part). The table below shows the value of the Z coordinate for each tool when this occurs.

Figure 1. Note the part zero location in the vertical (z) direction is located on the top surface of the part.

Table A:

Using the Large Offset Method, complete the table below for the tools shown in Table A:

Write G-code for each tool, so that the tool moves in a rapid motion to a point at which the tip of the tool is 0.2” above the part surface.

Tool1:

Tool2:

Tool3:

You have just machined a handle (0.5” thick) for manual crank on a pump. Now you need to machine a key (0.200” thick) for an electric motor shaft. Your program is ready. Do you need to modify any of your vertical parameters? Which ones?

Using the Reference Method, complete the table below for the tools shown in Table A. (Assume the original part is being machined.):

Write G-code for each tool, so that the tool moves in a rapid motion to a point at which the tip of the tool is 0.2” above the part surface.

Tool1:

Tool2:

Tool3:

You have just machined a handle (0.5000” thick) for manual crank on a pump. Now you need to machine a key (0.2000” thick) for an electric motor shaft. Your program is ready. Do you need to modify any of your vertical parameters? Which ones?
