To drill a quality hole in titanium material, you need to understand titanium materials and have good basic drilling knowledge and skills.
Estimated completion time (hours): 2.1
Objectives
By the end of this course, you will be able to do the following:
- List some qualities of titanium material
- Understand the hazards of working with titanium materials
- Define a quality hole
- Understand how to drill a quality hole in titanium material
- Recognize some common hole defects
Before holes are drilled in an assembly, their locations must be marked.
Estimated completion time (hours): 1.0
Objectives
By the end of this course, you will be able to do the following:
- Recognize hole location information on an engineering drawing
- Explain where to find the tools and other supplies needed to create an assembly
- Prepare the surface of an assembly for mark up
- Properly measure and mark hole locations in the assembly
In this course, you will be shown how to create the assembly and drill pilot holes.
Estimated completion time (hours): 0.9
Objectives
By the end of this course, you will be able to do the following:
- Create an assembly
- Properly secure the assembly in the vise
- Install a pilot bit in a drill motor
- Drill pilot holes into the assembly
After the pilot holes are drilled in rows JD1, and JD3 through JD8, drill the pilot holes in row JD2 and then enlarge them.
Estimated completion time (hours): 1.1
Objectives
By the end of this course, you will be able to do the following:
- Use a ninety-degree drill motor to drill the pilot holes in row JD2
- Use a ninety-degree drill motor and two separate single step drill bits to enlarge the pilot holes to size
The next row of holes to enlarge is row JD7.
Estimated completion time (hours): 0.8
Objectives
By the end of this course, you will be able to do the following:
- Enlarge the holes in row JD7
After enlarging the holes in row JD7, enlarge the holes in rows JD4, JD5, and JD6.
Estimated completion time (hours): 0.8
Objectives
By the end of this course, you will be able to do the following:
- Enlarge the holes in rows JD4, JD5, and JD6
After enlarging the holes in rows JD4, JD5, JD6, and JD7, enlarge row JD1 and JD3.
Estimated completion time (hours): 1.0
Objectives
By the end of this course, you will be able to do the following:
- Use two reamers to enlarge the holes in rows JD1 and JD3 to size
After enlarging the holes in all the other rows in the assembly, enlarge the holes in row JD8.
Estimated completion time (hours): 0.8
Objectives
By the end of this course, you will be able to do the following:
- Enlarge the holes in row JD8
Two rows in the final assembly require chamfers: rows JD4 and JD6.
Estimated completion time (hours): 1.0
Objectives
By the end of this course, you will be able to do the following:
- Choose appropriate scrap material
- Mark hole locations and drill and chamfer holes in scrap material
- Measure the diameter of a chamfer with a countersink gauge
- Adjust a countersink cutter to create a chamfer of the correct diameter
- Chamfer holes in the final assembly
Although no fasteners will be installed in this assembly, it is still important that you learn the final hole finishing procedures required for titanium assemblies.
Estimated completion time (hours): 1.4
Objectives
By the end of this course, you will be able to do the following:
- Edge break a hole to a specified diameter
- Inspect an edge break using a countersink gauge
- Deburr holes in a titanium assembly
