Machining and CNC Technolog
Pages : 886
Size : 90 MB
Programmed machine tools now represent nearly 100 per-
cent of manufacturing and, of greater impact to you, of new
jobs. Entry-level people usually start in the shop as CNC
operators. Flexible and friendly, the machines and program-
ing systems are so quick and easy to learn that they are now
practical even for one-of-a-kind work such as mold making
and die work, as well as production. Schools integrate and
teach CNC as an entry-level subject—starting from the fi rst
lesson on the fi rst day.
This book was specifi cally written to serve this type of
modern student. To do so, subjects have been grouped into
four large career partitions:
Part 1 Introduction to Manufacturing
Manufacturing is a world of its own. Chapters 1 through 8
are designed to open the door. They provide the background
needed to fi t into the shop, to understand the rules, to read
and interpret the drawings, to be comfortable with extreme
accuracy, and especially to be safe.
Part 2 Introduction to Machining
Chapters 9 through 16 teach how to cut metal the right way.
These lessons assume that you’ll eventually perform them
on CNC equipment, but will probably practice fi rst on manu-
ally operated machines because they are a simple, safe place
to learn setups and operations.
Part 3 Introduction to CNC
Now we get to the text core: how to apply Parts 1 and 2 to
setting up, programming, and running CNC machine tools.
In Chapters 17 through 24, we will learn how to profession-
ally manage a CNC world. Because they move at lightning
speed with lots of power behind them, safety must be inte-
grated into everything we study.
Part 4 Advanced and Advancing
Chapters 25 through 29 set the tone for your career after
graduation. The best is yet to come, so let’s get started!
