Introduction to selecting the proper punch and die for air bending or bottoming when forming on a press brake. Includes charts and methods for selection.

In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.

In this learning activity you'll review the steps for calibrating the length of depth micrometer measuring rods.

In this animated print reading exercise, the learner calculates missing dimensions and identifies surfaces on projected views.

Learners will determine if they are satisfied with their attitudes and then rank tips for regaining a positive disposition in the workplace.

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.

This document gives an overview of chuck maintenance.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.

In this learning activity you'll explore lathe tool-holding techniques.

This is a project that gives steps to complete the activity.

In this interactive object, learners read an explanation of the electrodes used for welding with the GMAW and FCAW processes. In two matching exercises, students test their knowledge of classification and specification numbers.

In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

The learner will understand how to use a cause and effect diagram to find the root cause of a problem.

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.

The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.

In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

Students view how the tool length offsets are set on the CNC Machine. They read a description of a method that uses a 2-inch gage block as a height reference.

In this interactive object, learners read a description of value-added and non-value-added activities and then place various work duties into these two categories.

Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.

Learners will understand the technical terms used in the context of the SDS to help them interpret its information.

Students test their skill at converting binary numbers to decimal numbers. Immediate feedback is provided.

Students read how to set up the optical comparator edge detector in this interactive learning object.

In this learning activity you'll review angles and different types of angular measuring tools associated with manufacturing.
