1. INTRODUCTION
Industrial revolution that had led to the emergence of modern era has its roots in the Lathe
machine. Widely known as the ‘Mother of machine tools’, Lathe works by removing materials
from a workpiece to give a desired shape and size. Various material removing operations such
as facing, turning, chamfering, knurling, grooving etc can be performed with it. In the past,
mechanized power generated by water wheels and steam engines was used to operate lathe,
imparting a certain degree of control to it. But it’s not until the 1950s that servomechanisms
were applied to the control, coupling with the computers to yield Computer Numerical Control
(CNC) lathe. Today CNC lathe machines are being used in almost all manufacturing industries.
1.1 Computer Numerical Control (CNC)
Computer Numerical Control or CNC refers to the automation of machine tools by using
computers executing pre-programmed sequence of machine control commands.
A simple CNC system
Taking digitized data fed into it by the user, a computer and CAD/CAM (Computer Aided
Design / Computer Aided Manufacturing) program is used to control, automate and monitor
the movement of the machine. The machine can be a lathe, milling machine, router, welder,
grinder, laser or waterjet cutter. CNC controller works with a series of motors and drive
components to move and control the machine axes, executing programmed motions.
1.1.1 Parts
1.1.1.1 Computer system and CAD/CAM
All modern CNC machines constitute a computer system with a CAD/CAM software into
which the user can feed in the CAD diagram or directly enter a set of commands called NC
code for the machine to understand.

1.1.1.2 Numerical Control or NC Code
Originally developed to program parts directly at the machine keyboard without any CAM
software, the Numerical Control (NC) codes tell the machine what moves to execute, one by
one, as well as controlling other machining functions like spindle speed, feed rate. The most
commonly used language is G-code or ISO code, a simple alphanumeric programming
language developed for early CNC machines. Instead, if a CAD diagram is fed, the
postprocessor in the program converts the diagram to the relevant NC code and pass it to the
Control Unit.
1.1.1.3 Control Unit
The control unit constitutes a controller, drives and circuitry for machine motion along multiple
axes, atleast two (X and Y), in the case of CNC lathe machine while a third axis (Z) can be
used to move the tool spindle as in the case of CNC milling machine. Stepper motors are used
for accurate control of the machining process resulting in high quality, accurate finishing.
1.1.2 Types of control
Open loop control, without any feedback can used for simple machining operations requiring
less accuracy and speed.
A simple open loop control
Closed loop control with feedback from sensors is used for increased accuracy, repeatability
and speed.

1.1.2 G-Code and M-Code
G-Code and M-Code are the most widely used Numerical Control (NC) programming
languages for the automation of machine tools. The codes constitute instructions to the machine
controller that tells the drives where to move, performing machining operation on the mounted
workpiece.
G-Code instruction specifically deals with the type of motion control required for machining
operation.

1.2 Lathe machine
Lathe is a machine tool that rotates the workpiece about an axis of rotation to perform various
operations like facing, turning, knurling, chamfering etc. using cutting tools to create objects
with symmetry about that axis.
Manual lathe machine
5
1.2.1 Parts of manual lathe machine
Main parts of manual lathe are as following;
1.2.1.1 Lathe Bed
The bed of the lathe machine is the base on which all other parts are mounted. It is horizontal,
massive and rigid single piece of casting made to support other active parts of the lathe.
Headstock and tailstock are located the two extremities of the bed. A guideway runs in between
holding the carriage for transverse axis. Generally, cast iron alloyed with nickel and chromium
material is used for manufacturing lathe bed.
1.2.1.2 Headstock
Head stock bears the horizontal axle parallel to the bed, called spindle. Spindles are often
hollow and have exterior threads for mounting work-holding accessories like chuck. Spindle is
driven by an electric motor via gearbox or belt to impart motion to the workpiece. In addition
to this, the headstock can also contain speed control methods for adjusting the spindle speed as
the machining requirement.
1.2.1.3 Carriage
The carriage runs on the guideway along the working length of the lathe. It carries the cross
slide, saddle, compound rest and tool post for the transverse movement and machining. It can
be adjusted to fit any angle for machining operation. The compound rest is actuated by a screw,
which rotates a nut fixed to the saddle. Tool post mounts the tool holder.
1.2.1.4 Tailstock
The tail stock is commonly used for the objective of primarily giving an outer bearing and
support the circular job being turned on centres. Tail stock can be easily set or adjusted for
alignment or non-alignment with respect to the spindle centre and carries a centre called dead
centre for supporting one end of the work. Both live and dead centres have 60° conical points
to fit centre holes in the circular job, the other end tapering to allow for good fitting into the
spindles. The dead centre can be mounted in ball bearing so that it rotates with the job avoiding
friction of the job with dead centre as it important to hold heavy jobs.
1.2.1.5. Feed Mechanism
Feed mechanism is the combination of different units through which motion of headstock
spindle is transmitted to the carriage of lathe machine.
The gearing at the end of bed transmits the rotary motion of headstock spindle to the feed
gear box. Through the feed gear box the motion is further transmitted either to the feed shaft
or lead screw, depending on whether the lathe machine is being used for plain turning or screw
cutting. The feed gear box contains a number of different sizes of gears. The feed gear box
provides a means to alter the rate of feed, and the ration between revolutions of the headstock
spindle and the movement of carriage for thread cutting by changing the speed of rotation of
the feed rod or lead screw. The apron is fitted to the saddle. It contains gears and clutches to
transmit motion from the feed rod to the carriage, and the half nut which engages with the lead
screw during cutting threads.

5.2 Experiment 2 – Step Turning using CNC Lathe
Aim: To machine the given work piece according to the dimensions given in diagram using
CNC Lathe
Tools required:
Chuck key
Tool post spanner/ Hex key
Turning tool
Chamfering tool
Vernier Calliper
Steel rule
Power supply
Software required:
GrblGru V.3.7.0
Arduino 1.8.1
Universal G-Code sender
Procedure:
1. The work piece is held in the lathe chuck.
2. The cutting tool is held in the tool post and its cutting point is set to lathe axis using
reference from the open source software.
3. Import the drawing in. stl /.nc/.dxf into the software
4. Make sure the drawn piece is imported within the specific parameters. Otherwise
resize the work piece into appropriate dimensions.
5. Fix the feed cut parameters and tolerance level and fix the tool piece at the centre.
6. Once the outer diameter of the piece is set we can start simulating the feed cut
machining
7. Save the simulated piece by converting it into G-code using the G-code creator
button.
8. After the G code is generated, switch on the power source and start rotating the chuck
and spindle setup. (make sure that the tool post is set to pre-set origin before
commencement of running the code)
9. Commence the transmission of code into the universal G-code sender and start the
process by pressing the send button.
10. Automatically the facing and plain turning operation are carried out as per the given
dimensions.
11. After the plain turning operation is completed the tool is fed parallel to the lathe axis
to the particular length assigned by the code.
12. Two or more cuts are given accordingly to retrieve the required diameter.
13. Now the first step of machining is completed and by repeating the same process the
CNC lathe comenses its operation with the specified diameter.
14. By this time the work piece would be completed.

Result:
The given work piece is machined according to required dimensions by the CNC lathe
according to the code given by the universal G-code Sender

5.3 Experiment 3 – Taper Turning using CNC Lathe
Aim: To machine the given work piece according to the dimensions given in diagram using
CNC Lathe
Tools required:
Chuck key
Tool post spanner/ Hex key
Turning tool
Chamfering tool
Vernier Calliper
Steel rule
Power supply
Software required:
GrblGru V.3.7.0
Arduino 1.8.1
Universal G-Code sender
Procedure:
1. The work piece is held in the lathe chuck.
2. The cutting tool is held in the tool post and its cutting point is set to lathe axis using
reference from the open source software.
3. Calculate the taper angle using the formula
4. Prepare drawing using drawing tools and import the drawing in. stl /.nc/.dxf into the
software.
5. Make sure the drawn piece is imported within the specific parameters. Otherwise
resize the work piece into appropriate dimensions.
6. Fix the feed cut parameters and tolerance level and fix the tool piece at the centre.
7. Once the outer diameter of the piece is set we can start simulating the feed cut
machining
8. Save the simulated piece by converting it into G-code using the G-code creator
button.
9. After the G code is generated, switch on the power source and start rotating the chuck
and spindle setup. (make sure that the tool post is set to pre-set origin before
commencement of running the code)
10. Commence the transmission of code into the universal G-code sender and start the
process by pressing the send button.
11. The step and plain turning process operation are carried out according to the
prescribed dimensions.
12. Then the taper angle cut operation is done and the work piece is finished.
Result:
40
The given work piece is machined according to required dimensions by the CNC lathe
according to the code given by the universal G-code Sender

6. CONCLUSION
A low cost DIY CNC Lathe machine has been designed and developed using conventional
off the shelf components of open source hardware and software, and sample sets of
experiments have been performed.
Current design uses wooden frame and will be replaced with mild steel for improved
strength, rigidity and durability. The next version will also aim at machining non-ferrous
metal workpiece with a higher degree of accuracy by incorporating sensors to it.
Addition of limit switches and associated sensors will provide feedback for optimum control
during machining operation and good accuracy.
