TYPES OF MACHINING
• Drilling
• Cutting
• Bending
![Page 13: Efficient Robot Fabrication](https://reader035.vdocuments.us/reader035/viewer/2022062323/568166de550346895ddb0a5f/html5/thumbnails/13.jpg)
TOOLS NEEDED• Marker or drawing utensil
• Punches
• Ball Peen Hammer
• Combination Square
• Dial Calipers
• Correct Size Drills (sometimes smaller bits)
![Page 14: Efficient Robot Fabrication](https://reader035.vdocuments.us/reader035/viewer/2022062323/568166de550346895ddb0a5f/html5/thumbnails/14.jpg)
HOW TO DRILL PRECISE HOLE LOCATIONS1. Know where your hole is
2. Measure and mark it
3. Measure it again
4. Center Punch
5. Drill pilot hole if needed
6. Drill with a full sized bit
7. Debur the hole

DRILLING TIPS AND TRICKS
• Use a punch
• Above ¼ in, drill starter hole
• Oscillating pressure with hole saws

CUTTING TIPS AND TRICKS
• Start with strips of smallest dimension
• Keep leftover strip if still big enough to be useful
• Irregular parts, use CAD
• On some tools allow space for the blade

CUTTING TIPS AND TRICKS (CONT.)
• Shaft
• Add 1/8th inch to wanted length
• Turn as you cut
• File edge to a chamfer
![Page 18: Efficient Robot Fabrication](https://reader035.vdocuments.us/reader035/viewer/2022062323/568166de550346895ddb0a5f/html5/thumbnails/18.jpg)
CUTTING TIPS AND TRICKS (CONT.)
• Extrusion
• Do not add 1/8th
• Hand File sharp edges
• Avoid chamfer

BENDING TIPS AND TRICKS
• Draw Bend Line
• Compensate for bend radius
• Make jig if needed
• Over bend for elastic materials

• Other tools you can use
• Vise
• Wood board
• Hammer

FASTENERS
• Nuts and Bolts
• Screws
• Adhesives
![Page 22: Efficient Robot Fabrication](https://reader035.vdocuments.us/reader035/viewer/2022062323/568166de550346895ddb0a5f/html5/thumbnails/22.jpg)
NUTS AND BOLTS• Nuts
Come in different shapes to suit different purposes
Lock nut
T-nut
• Bolts
Come in a multiple sizes and heads
![Page 23: Efficient Robot Fabrication](https://reader035.vdocuments.us/reader035/viewer/2022062323/568166de550346895ddb0a5f/html5/thumbnails/23.jpg)
SCREWS• Most of the time used with wood
• Can be done with metal
• Bolt and Screw can be used interchangeably only difference is in application
