Machine Shop Practices
The Machine Shop Practices training series is a nine course program that begins with an explanation of the types of tools used in machining. The following courses continue on to include step-by-step setup directions for turning and shaping operations. In-depth courses are full of illustrations and animations to make every point as clear as possible. Each training topic is reinforced with the latest programmed learning techniques.
Covers the principles of machining, measurement, tool grinding, and machine shop safety. This course discusses the properties of metals, how to lay out and set up a job, how to use measuring devices such as the micrometer and vernier caliper, and how to read working drawings. Explains how to grind single-and multi-point tools.
Lesson 1 – Principles of Machining
Lesson 2 – Layout Work and Shop Safety
Lesson 3 – Setup Tools
Lesson 4 – Setup Measurement
Lesson 5 – How to Grind Single-Point Tools
Lesson 6 – How to Grind Multi-Point Tools
Covers the major types of lathes and their attachments, safety, maintenance, job preparation, and basic lathe operations. This course discusses all facets of drilling and boring, types of drills and drill presses, milling machines, and job bores. Explains reaming and reamer terms.
Lesson 1 – Lathes and Attachments
Lesson 2 – Basic Lathe Operations
Lesson 3 – Drilling and Boring
Lesson 4 – Reaming
Lesson 5 – Threads and Threading
Covers types of milling machines and milling operations. Covers spindles, arbors, feed rates, and safety precautions. This course discusses shaper and planer operations-setup, maintenance, and safety procedures. Also introduces grinding, power sawing, and gear cutting operations.
Lesson 1 – Milling Operations
Lesson 2 – Shaping and Planing
Lesson 3 – Grinding Operations
Lesson 4 – Gear Cutting
Lesson 5 – Power Sawing
Covers types of jobs likely to be encountered by the maintenance machinist, and describes how the machinist decides which machine(s) to use for particular operations. This course shows how to analyze the entire job before selecting the most efficient sequence of machining operations. Builds on Courses 315, 316, 317, and is a prerequisite for the “hands-on” projects in the courses that follow.
Lesson 1 – Machining Cylindrical Shapes
Lesson 2 – Drilling, Reaming, and Honing
Lesson 3 – Machining Flat Surfaces
Lesson 4 – Determining Tolerances and Finishes
Lesson 5 – Variables Affecting Job Efficiency
The course takes the trainee through a series of operations on the lathe to make a student project (a plug gauge). Covers lathe setup, rough turning procedures, finish turning, and chamfering. Next the course covers shouldering, knurling, and notching operations. Finishes with external thread cutting and marker tapers.
Lesson 1 – Lathe Setup and Workpiece Preparation
Lesson 2 – Rough and Finish Turning
Lesson 3 – Shouldering, Knurling, and Notching
Lesson 4 – Cutting External Threads
Lesson 5 – Turning Tapers Between Centers
A sequential follow-up to course 324 on lathe operation, This course covers chuck installation, boring and counterboring operations, thread cutting, and taper boring. Continues into special lathe operations that use faceplates, angle plates, and boring bars. Provides several real “hands-on” projects.
Lesson 1 – Lathe Setup and Workpiece Preparation
Lesson 2 – Rough Turning and Finish Turning
Lesson 3 – Boring and Counterboring
Lesson 4 – Cutting Internal Threads and Boring Tapers
Lesson 5 – Holding Irregular and Oversize Workpieces
The Basic Milling Procedures course covers the setup and use of the horizontal milling machine, and describes the functions of basic cutters and attachments. Uses “hands-on” projects so trainees actually gain experience on the milling machine. Includes a work-holding fixture project that can have practical value in the shop when finished.
Lesson 1 – Using the Horizontal Milling Machine
Lesson 2 – Slab Milling Procedures
Lesson 3 – Milling Slots and Angles
Lesson 4 – Straddle, Side, and Face Milling
Lesson 5 – Milling Keyseats, Squares, and Flats
Covers the use of the dividing head. Covers plain, differential, and angular indexing. The course explains the use of the dividing head for milling hexagons. This course proceeds to the cutting of spur gears, helical gears, and cams.
Lesson 1 – Using the Dividing Head
Lesson 2 – Dividing Head Setup
Lesson 3 – Milling Spur Gears
Lesson 4 – Helical Milling
Lesson 5 – Milling Cams
Previous courses have dealt largely with the operation of two major machine tools, the lathe and the milling machine. This course picks up some of the other machines found in a machine shop, some of which may be used infrequently, but which nevertheless require specific skills to operate. In most cases, simple projects are described to give trainees experience working with these machines.
Lesson 1 – Power Sawing
Lesson 2 – Drilling Operations
Lesson 3 – Operating a Horizontal Shaper
Lesson 4 – Grinding Operations
Lesson 5 – Boring Mill Operations
