I was showed, in the lecture, how to use a metal machine in safe manner to create the object and shapes of the metal parts which can be useful for machines. Next tutor took us to the metal workshop, explained the instruction to use the machine safely. He showed us the instruction of using guillotine, bending machine and Lathe machine.
Then he told us to practice what we learn from the lecture about how we can creates metal shapes with mechanical machine safely by showing not to touch the spinning spindle and wok piece to protect my self and others from injuries when we were working in workshop.
First i learned that Lathe machine is operate mainly by the spinning spindle with chuck that attached to work pieces, then letting the cylinder work pieces getting in contact with the cutting tools to create the symmetrical shape out of it. I can also drill a hole into cylinder as well as taking small materials out side the rod. You can make a steel ring, furniture or car engine gears. Lathe can shape many material such as plastic, woods and Steels.
The one that i used was the physical guillotine it function by laying sheet metal on bed, next insert the sheet metal under the blade then i have to put my leg force into blade handle to cut the sheet.
Tutor showed us how to use the hand folding sheet metal machine in safely. it worked by opening the metal clamp by pulling the clamp hinge bar upward, next insert the sheet metal between bed and metal clamp. Close the clamp down to hold the sheet metal against bed and clamp by pulling the hinge bar handle downward again.
Finally A hinged bending "leaf" is lifted to fold the metal around the fulcrum point of the clamping bar to the desired angle which is controlled using a stop rod. A box and pan brake machine is needed to avoid having the metal hit against the clamping bar when the 3rd and 4th sides are being bent. This is done by removing a "finger" from the clamping bar at each end of the box since the clamping bar is divided up into many sub-assemblies called "fingers".
I also learned the instruction to use hole punch tool to create holes out of a sheet metal by putting sheet metal underneath the pin then pressing the handle to put the hold to the sheet.
then I created my own my sheet metal parts with guillotine, metal folder and hole punch tools as tutor told me to do.
Tutor also showed us the XYZ Mini Mill which functioned similar to the Lethe machine except that it can be create any shape just using drilling pin to drill out the small pieces out of the block.
This machine is function when the engineer insert the data of the design of the shape they want to make by make into the machine system.
