lesson plan on drill press

1. Theory Lesson Plan
School: St Andrew Technical High
Teachers:
Subject: Mechanical Technology
Grade: HE10A
Date:
Room:
Time of class: 8:00am-9: 40am
Duration: 100 minutes
Unit Topic: Drill Press
Sub-topic: Tool & Work Holding Devices
Number of Students: 25

2. General Objective:
Students should:
1.0 Know the types of work holding devices used on the drill press
2.0 Know the types of tool holding devices used on the drill press.
Specific Objectives:
At the end of the lesson students should be able to:
1.1 Identify at least four (4) method of holding work on the drill press.
1.2 Explain four work holding devices used on the drill press.
1.3 Identify and explain the method of holding the cutting tool on the drill press
Rationale:
Work holding and tool holding devices are very important because of the number of operations
done on the drill press. It is very important that all students know the different types of work
holding devices used on the drill press. This will assist students when performing operations on
the drill press to properly select the work holding device that best fits the criteria of the job
requirements. At the end of the lesson students should be able to select the correct work holding
device needed for their job or task.

3. Previous Knowledge:
Students were introduced to the number of operations that can be performed on the drill press.
They were also given a project that involves work holding devices on the machine.
Instructional Strategy:
 Discussion-
 Explanation
 Illustration
 Question and Answer
Materials/Equipment/Media:
 White board
 Teacher notes
 Power Point Presentation
 Projector
 Samples of work holding devices

4. Condition: Students will be given:
 Oral presentation
 Well ventilated classroom with accurate space, for the student to work in
groups or individually
PERFORMANCE STANDARDS:
 Students are expected to answer questions in accordance to information given.

Introduction:
The teacher will start the class by giving a brief summary of the previous lesson, by recapping
some operations that can be done on the machine. The teacher will ask students to list some of
the operation discussed at the last class. The teacher will raise situations that need special work
holding device and ask questions as it related to the situations. At the end of the question and
answer session the teacher will project the types of work and tool holding devices on the board

5. by means of a multimedia projector .The teacher will then ask the student to take notes from the
PowerPoint presentation.
