ABSTRACT:
The application of science to technology is very evident in this laboratory activity that students
report as one of the highlights of their school year. This session will demonstrate how the application of
technological advances can affect us, using the excitement of creating student-designed 3-dimensional
objects. A photoactive polymer is initiated by the UV light emitted from a simple data projector. This
causes the formation of free radicals which interact with a monomer, causing an addition
polymerization reaction. The visual result of this is that where you shine light, the liquid solidifies.
Using black and white images that students can create with PowerPoint or a similar software tool, a data
projector can direct the light to form any shape. This process can be easily modified to instead create
true 3-D objects by adding another layer of the liquid to the top of the object and shining the light again.
a simple staging device can be created to greatly simplify the process of creating a 3-D printer in the
classroom. This lab integrates engineering with chemistry for an interdisciplinary activity and is based
on research being conducted at the University of Illinois in which this process is being used to create
very small objects.
DESCRIPTION:
In new product development, time to market (TTM) is critical for the success and profitability
of next generation products. When these products include sophisticated electronics encased in
3D packaging with complex geometries and intricate detail, TTM can be compromised -
resulting in lost opportunity. The use of advanced 3D printing technology enhanced with
component placement and electrical interconnect deposition can provide electronic prototypes
that now can be rapidly fabricated in comparable time frames as traditional 2D bread-boarded
prototypes; however, these 3D prototypes include the advantage of being embedded within
more appropriate shapes in order to authentically prototype products earlier in the development
cycle. The fabrication freedom offered by 3D printing techniques, such as stereolithography
and fused deposition modeling have recently been explored in the context of 3D electronics
integration - referred to as 3D structural electronics or 3D printed electronics. Enhanced 3D
printing may eventually be employed to manufacture end-use parts and thus offer unit-level
customization with local manufacturing; however, until the materials and dimensional
accuracies improve (an eventuality), 3D printing technologies can be employed to reduce
development times by providing advanced geometrically appropriate electronic prototypes.
This paper describes the development process used to design a novelty six-sided gaming die.

CONFIGURATION OF CNC SYSTEM
Fig shows a schematic diagram of the working principle of an NCaxis of a CNC machine and the
interface of a CNC control.A CNC system basically consists of the following:-
•Central processing unit (CPU).
• control unit
•Operator control panel
•Machine control panel
•Other peripheral devices
•Programmable logic controller Figure gives the typical control configuration of Hinumerik 3100
CNCsystem.
1.Central Processing Unit (CPU) :-
The CPU is the heart of a CNC system. It accepts the
information stored in the memory as part program. This data isdecoded and transformed into specific
position control and velocity signals. It also oversees the movement of the control axis or spindle and

whenever this does not match with the programmed values, acorrective action as taken.All the
compensation required for machine accuries (like
leadscrew pitch error, tool wear out, backlashes.) are calculated by CPUdepending upon the
corresponding inputs made available to the system. The same will be taken care of during the
generation of control signals for the axis movement. Also, some basic safety checks are built into the
systemthrough this unit and continuous necessary corrective actions will be provided by CPU unit.
Whenever the situation goes beyond control of the CPU, it takes the final action of shutting down the
system and in turn the machine.
INTRODUCTION OF CNC MACHINE
2.Servo control unit :-
The decoded position and velocity control signals, generated by the CPU for the axis movement forms
the input to the servo control unit. This unit in turn generates suitable signals as command values .The
command values are converted by the servo drive units which are interfaced with the axes and
the spindle motors.The servo control unit receives the position feedback signals for the actual
movement of the machine tool axes from the feedback devices (like linear scales, rotary encoders,
revolvers, etc.)
3.Operator Control Panel :-
The Operator Control Panel provides control panel provides the user interface to facilitate a two way
communication between the user, CNC system and the machine tool. This consists of two parts;
•Video display unit
•Keyboard
4.Machine Control Panel :-
It is the direct interface between the operator and the NC system, enabling the operation of the machine
through the CNC system .During program execution, the CNC controls the axis the motion, spindle
function or tool function on a machine tool, depending upon the part program stored in the memory.
Prior to the starting of the machining process, machine should first be prepared with some specific
takes like,
•Establishing a correct reference point
•loading the system memory with the required part program
•Loading and checking of tool offsets, zero offsets, etc
5.Other peripheral devices :-
These include sensor interface, provision
for communication equipment, programming units, printer, tape reader interface, etc.

6. Programmable logic Controller:-
A PLC matches the NC to the machine. PLC’s were basically as replacement for hard wired relay control
panels. They were basically introduced as replacement for hard wired relay panels. They
developed to be reprogrammed without hardware changes whenrequirements were altered and thus
are reusable. PLC’s are nowavailable with increased functions, more memory and larger input/output
capabilities.In the CPU, all the decisions are made relative
tocontrolling a machine or a process. The CPU receives input data, performs logical decisions based
upon stored programs and drives theoutput s. connection to a computer for hierarchical control are done
via the CPU.
