In session 1 we learned about material processing, the history of the manufacture and some inventions that were important to manufacturing. We also learned how to operate the Z-mill and some basic steps to take while working with it.
In session 2 we learned why tolerances and specifications are important when manufacturing something. We also learned how to measure and mill a simple geometric shape using the manual buttons on the Z-mill.
In session 3 we learned the machine movements and the various speeds that the Z-mill has. We then manually etched various shapes into the milling project that we started in the last activity.
In session 4 we learned about the Cartesian coordinate system. We also learned how the z-mill and the Cartesian coordinate system relate. After that we learned about the computer software for the z-mill And then we made different geometric shapes.
In session 5 we learned about the z-mill software more. We then made a nameplate with the software. After that we engraved it into the drilling material.
In session 6 we used the z-mill to prepare to make a pre-drawn graphic.We then chose a graphic of our choice and drilled it into the pitsco drilling tool.
In the last session, session 7 we completed a challenge made for us using the z-mill software.
The CNC programmer constantly refers to drawings and CAD programs to ensure codes are entered in the correct sequence. Once the professional is confident in the program, he or she can put the machine through a series of test runs to make sure it works correctly. The programmer notes any discrepancies between test products and blueprint specifications, and adjusts his or her program accordingly. Once a program is perfected, it can be implemented across a number of machines to begin the mass production of the item.
