In this learning activity you'll explore the history behind gage blocks.

In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

Learners examine the information on a title block and answer questions about that information in an interactive quiz.

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

In this learning activity you'll explore Lathe Turning Machines.

The learner will understand the basics of machine turning including how a lathe works, the equipment used, and commonly used terms.

In this simulation, learners follow steps to clear out a job that had been previously created.

The learner will measure and record dimensions using a metric micrometer to an accuracy of plus or minus .01 of a millimeter.

In this learning activity you'll review how to read a metric micrometer and use your knowledge to answer 12 questions.

In this video, you’ll explore how to use a vise on a Bridgeport mill to securely hold your workpiece.

In this interactive object, learners set up a shear, enter the back gauge dimension, and prepare to shear metal in a simulation of the Adira Hydraulic Shear.

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

In this interactive learning object, learners read how to compensate for a part not mounted perfectly parallel to the machine axis.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

In this video, we’ll identify the parts that make up the Bridgeport and learn how it works.

Learners examine the relationship of individual parts in an assembly drawing. Assembly drawing notes, fabricated and purchased parts, and sectional views are explained briefly.

Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.

The student reads about the procedures for loading punches and turning a die block in an up-acting hydraulic press brake. The safe handling of press brake tooling is also illustrated.

Learners test their ability to visualize an angled mount in this interactive exercise that features animated pictorial views.

Learners practice reading prints of a hub. They identify information located on the print and calculate missing dimensions.

In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

Learners test their ability to visualize a holder in this interactive exercise that features animated pictorial views.
