Files, Hand Reamers, and Lapping Tools

Files, hand reamers, and lapping tools are used to shape materials. The shapes created with these tools include flat surfaces, curved surfaces, and precision holes. Each tool requires knowledge of the tool and its use to make products that meet the requirements of an engineering drawing. By the end of this course, you will be able to • Explain the purpose and function of a file • Identify the major components of a file • List the most common types of files • Define and describe the purpose of a hand reamer • Discuss the use of an adjustable hand reamer • Define and describe the purpose of a lapping tool • Describe the purpose of lapping compounds

Scribes, Optical Center Finders, and Drill Blocks

An important part of creating tooling is defining patterns and the locations of holes for cutting and drilling. Toolmakers use optical center finders and scribes in combination with templates when laying out tooling and drill blocks to ensure holes are drilled correctly. By the end of this course, you will be able to • State the purpose of layout dye • Describe how layout dye is removed after machining • Explain the use of scribing tools • Describe the purpose of an optical center finder • Describe the purpose of a drill block
