Backwards Design

Course Objectives

• Primary Objectives- By the next class period students will be able to:
• Measure to 1/64” (0.5 mm) with a steel rule.
• Measure to 0.0001” (0.002 mm) using a Vernier micrometer caliper.
• Measure to 0.001” (0.02 mm) using Vernier measuring tools.
• Measure angles to 0°5’ using a universal Vernier bevel
• Identify and use various types of gages found in a machine shop.
• Use dial indicator.
• Employ the various helper measuring tools found in a machine shop.

• Sub Objectives- The objectives will require that students be able to:
• Know safety on handling tools.
• Apply safety procedures in lab.

• Difficulties- Students may have difficulty:
• Identifying tools
• Properly using some of the helper measuring tools.
• Properly using the dial indicator.
• Using the Vernier Micrometer.
• Identify the proper use of various gages.

• Real-World Contexts- There are many ways that students can use this material in the real-world, such as:
• Many applications implement the use of basic tools and simple measurements with the steel rule.
• Learning the above concepts and acquiring the knowledge on basic hand tools and their proper use in Beginning Machining are the basis for any students looking into an manufacturing industry career for example a machinist, machine operator and CNC programmer.

THE CHALLENGE

You are working as a project manager in a wheel manufacturing company and you are assigned to put toghether a tools list needed to build the rims for a new camero.

GENERATE IDEAS

Students will be asked to get in groups of three and generate ideas regarding the challenge and various possibilities.

MULTIPLE PERSPECTIVES

RESEARCH & REVISE

Present lecture Gather information on rim design
