What Students Learn:
Preview
Since the development of machinery, there has been a war against friction. Friction causes machinery to vibrate excessively, sound louder, use more energy to do a given job, and, most importantly, wear out faster. To counter friction, lubricants have been developed.
Lubricants were once basic animal fats and plant oils used on simple machines. Today's lubricants are chemical compositions specially designed for specific types of machines and their work environment. There are now hundreds of types of oils and grease to select from, each tailored specifically for the machine or an individual component of any given machine.
This study unit is designed to give students the information they need to understand how lubricants are blended into these very special compounds and how they are selected for various applications.

This study unit is a basic introduction to the lathe. Trainees will become familiar with general terminology, and you will learn about the lathes operation. This unit is the first in a series of units on lathes. Each unit progressively discusses lathes in more detail. This unit is designed to give you background information, which equips you with a basic understanding of how to operate a lathe safely and efficiently. If you have just begun to work with lathes, you will find this basic information very helpful.
This unit uses both the English and Metric standards of measurement. Most examples use the English standard system, with the Metric equivalents listed. Not all conversions are held to a close tolerance. In cases where there are ranges of numbers, the nominal metric equivalents are given rather than the actual converted number. Trainees will find that, in practice, dimensions on a print will need to be converted directly. However, stock sizes, standard sizes, and ratings generally have nominal metric values close but not equal to English values.

Preview
Think of the types of energy used in most manufacturing processes. A lathe employs mechanical energy to remove material from the work piece. The tool makes contact with the work piece and the resulting shear causes the material to flow over the tool. All traditional forms of metal cutting use shear as the primary method of material removal. The primary source of energy in traditional manufacturing is mechanical. However, there are other sources of energy at work. Chemical energy has a significant effect on every turning operation. Think of the effect that different kinds of coolants have on the cutting action of a tool. Some amount of chemical energy is being used in most metal cutting operations. All forms of manufacturing use more than one type of energy. Nontraditional machining can be thought of as operations that do not use shear as their primary source of energy. For example, abrasive water jet operations use mechanical energy, but material is removed by erosion. In this study unit, students will learn more about nontraditional machining technologies.
When a student completes this study unit, he and she will be able to:
Explain how electrical discharge machining (EDM) works.
Describe the difference between wire and ram EDM.

What Students Learn:
Preview
Trainees have studied the process of machining and the various types of machine tools that are used in manufacturing. In this study unit, they will take a closer look at the interface between the machine tools and the work piece, the toolholder. In today's modern manufacturing environment, many sophisticated machine tools are available, including standard types and CNC machines with special accessories to aid high-speed machining. Many of these new machine tools are very expensive and have the ability to machine quickly and precisely. However, if a careless decision is made regarding a cutting tool and its toolholder, a poor product quality will result, no matter how sophisticated the machine. In this study unit, trainees will learn some of the fundamental characteristics that most toolholders have in common, and what information is needed to select the proper toolholder.
Objectives
When a student completes this study unit, he and she will be able to:
Understand the fundamental characteristics of toolholders required for various machine tools.
Understand and describe how the toolholder affects the quality of the machining operation.
