Lesson Plan Originally Created By: Dick Piersma

Project - Oxy-Acetylene Cutting

Part of Unit: Projects

Lesson Plan Overview / Details

This lesson is a hands-on project designed to assess the students' skills learned during the Oxy-Fuel Cutting Unit.  Students will be required to layout markings on a piece of steel and then make quality cuts using the O/A Cutting process according to specific instructions on a set of plans.  Students will be evaluated on safety, quality of cuts, and ability to follow instructions.

It is assumed that the students have received instruction and practice in the following areas:

  1. Oxy-Fuel Cutting safety
  2. Oxy-Fuel Cutting set up and shut down
  3. Oxy-Fuel Cutting: Straight , piercing, and bevel cuts

This project may be used as an assignment or as a test.

Objectives and Goals

  • By successfully completing this project students will be able to: 1) Read a plan to obtain critical information and dimensions, 2) Measure and layout a project on metal, 3) Safely set-up, operate, and shut-down the Oxy-Fuel Cutting set up, and 4) Safely demonstrate how to flame cut mild steel with an 80% degree of accuracy.
  • The goal of this project is to help the student to evaluate their Oxy-Fuel Cutting skills. Knowledge of project layout and the ability to follow directions will be tested as well.

Activities in this Lesson

  • Project Introduction - Hooks / Set

    Inform the students that this project will evaluate all of their cutting skills to date. Since the students have been practicing their cutting skills for the past few weeks, they will understand that this project will be a culmination of all that they have learned so far.

    Discuss with the students the importamce of being able to follow instructions when it comes to producing a product or performing a task using the Oxy-Fuel Cutting set up.

  • In this section you will review the project with the students paying close attention to the critical aspects of the project.  Use the student packet and the teacher's packet to review and demonstrate the process you want them to follow.

    • Oxy-Fuel Cutting Student Packet [ Download ] The student packet contains information on the materials and tools needed to complete the project, directions, room for notes, a set of plans, and a student worksheet and grading rubric.
    • Oxy-Fuel Cutting Teacher Packet [ Download ] The teacher packet contains all of what the student packet has as well as objectives, suggestions for alternate tools and materials, suggestions for safety review, demonstration tips and notes, and a bill of materials.
  • The students will need 3-5 class periods to complete this project.  Make sure you give the students clear instructions on how you want them to rotate around the shop to make the best use of your space and tools (put these instructions in a handout?).

    Be available to assist the students as needed as you will likely encounter Oxy-Fuel Cutting set up issues and to help students to best correct their mistakes.

    You will also need to decide what to do when a student seriously messes up their project and has to do a new one.  If you allow unlimited re-dos, you will go through a lot of materials.  I recommend that you limit re-dos to 1 so that students are motivated to do their best work.

  • Shop Management - Closure

    This activity will take place at the end of each Lab/Shop session.  It is important to have prepared some sort of an organized clean-up routine.

    Things to consider are:

    1.  Accounting for and putting away tools.

    2.  Storage of materials and supplies till the next Lab/Shop session.

    3.  Storage of partially finished or finished projects.

    4.  Clean-up of the shop (ie. sweeping).

    Recommendation:  Since this project will take 3 to 5 Lab/Shop sessions, split the class into 4 groups and assign each group to complete one of the items on the list above and rotate the groups each day.
