Quality Basics: Variation
By Mary Lee Rudnick-Kaun
Learners read an explanation of variation and how it can make a process unpredictable. They distinguish between common and special causes of variation in a brief exercise at the end of the lesson.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Setting Shielding Gas Flow for Wire Feed Welding
By Dave Hoffman
In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.
OR Gates
In this learning activity you'll review how an OR gate operates using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
Gage Blocks
By Barbara Anderegg
In this learning activity you'll explore the history behind gage blocks.
Logic Probes
In this animated activity, learners examine the fundamental operation of a logic probe that is used to detect logic signals in a digital circuit.
Using an Indicator

Using a Sine Bar
By Janet Braun
The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.
Surface Finish
Learners review surface finish basics and read how to calculate the roughness average.
Calculating Feed Speeds for Twist Drills
Students read how to calculate feed rates for drills in inches per minute (IPM). The IPM formula is given and students work two practice problems.
Power Dissipation
By Patrick Hoppe
Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.
Variation in Manufacturing: The Stable Process
By John Stewart
Learners read a brief introduction to in-control and out-of-control conditions and view a series of distribution curves. This is a follow-up to the learning object titled "Quality Basics: Variation."
