INTRODUCTION

CNC turning produces parts by "turning" rod material and feeding a cutting tool into the turning

material. In CNC turning the cutter can be fed into the rotating workpiece at a variety of angles

and many tool shapes can be used.

CNC turning provides an economical way to make parts that are commonly symmetrical about

an axis of revolution (e.g. a chess pawn). Shapes that can be made using CNC turning include a

variety of plain, taper, contour, fillet and radius profiles plus threaded surfaces. Although many

turned parts use a single axis of revolution, there can be multiple axis to allow more flexibility

(e.g. camshafts). CNC turning can be combined with CNC milling and other processes to make

more diverse shapes.

CNC turning can shape most rigid materials such as:

i. Aluminum

ii. Stainless Steel

iii. Copper

iv. Nylon

v. Steel

vi. Acetal

vii. Polycarbonate

viii. Acrylic

ix. Brass

x. Teflon

xi. Titanium

xii. ABS

CONCLUSION

As a conclusion, I have learned a lot of things about this CNC turning machine. I knew how to

handle this machine and its safety precautions. This machine is quite easy to handle and I very

excited when handle it. This knowledge is very useful to me and I hope that I can apply it when I

work one day.
