OBJECT COPIER OPERATION
The object copier consists of two parts.
1. Assimilation pod
2. Assembly line / Industrial process.
ASSIMILATION POD
It is a cylindrical shell which vary in size based on the object to be copied. It is mainly composed of 4 components.
a.
b.
c. Object stand: It holds the object to be copied in place. It must be made up of a highly inert metal such as platinum to avoid interaction with the laser array.
d. Laser array: It consists of 4 separate bent laser generators consisting of 3 to 4 pores each held together by an electrical or magnetic current. Since they are not connected by a solid they can expand to copy larger objects. He Ne source is used for the laser.
ASSEMBLY LINE
It resembles an automobile assembly system. It consists of a BASE COLLECTOR and STANDING LASER ARRAY… These are connected to a top surface. The base collector is made up of HSLA steel and working of the standing laser array is similar to the working of the laser in the assimilation pod.
The assembly line also consists of WORKPIECE ASSEMBLER consisting of two movable arms made up of HSLA steel.
Then it consists of a unit where welding and molding of the object is done if required.
There is a CONVEYER BELT on which the object moves. If there is any defect in the created object it is sent back through this belt for recycling.
WORKING
The laser in the assimilation pod is generated by a He Ne source and enhanced by quartz crystals. Laser will have shorter wavelength to ensure higher penetration ( UV- IR).
The object to be copied is placed on the object stand. Now the information regarding the material of the object, its size, composition pattern, its density, hollowness, mass and volume, appearance (colour) etc… are to be collected. For this.. the working is as given below.
After the object is placed (manually) on the object stand, the four laser arrays moved down from the
The four pores present on each laser array helps in scanning the 3 dimensional image of the object. Out of the 4 pores present two are the emitter pores which emits the laser energy and the other two are absorber pores which collects the incident radiation and it transfers these radiation to the laser capture plate from which the information is transferred to the computer. The laser is focused and scanned across a photoactive selenium coated drum where it produces a charge pattern which mirrors the information of the object to be copied. The pod is connected to a main frame computer which records the details of the object in the atomic level. Different software’s are used and thus a 3 d model of the object placed can be obtained in the computer.
The main frame is connected to an automated assembly line with all necessary raw materials to create copies of the original object.
The base collector places the basic material required for the creation of the object on the conveyer belt. The materials collected are first collected from the storage area in large space which is present below the belt. Here the materials are to be stored and refilled from time to time manually. The base material thus collected then passes to the workpiece assembler where all the other materials are provided and the arms provided does all the required bending, shaping, designing of the material.
If any welding or molding is required it is sent to the next unit where these process are done with the help of a gas welder.
The created object is then sent to standing laser array which is similar to that of the pod which will match the atomic signatures of the objects.
If there are any defects in the object it is again sent back to storage unit for recycling through the conveyer belt. If the obtained object is perfect it is collected from the other end of the conveyer belt.
Hence the object is replicated!!!
EMBODIMENT
· Good and efficient lead coating to be given so there is no leakage of laser radiations.
· The Assembly line (mainly in the base collector and to the arms in the workpiece assembler) should be lubricated once in a month for smooth running.
· Raw materials should be refilled from time to time manually. This can be done by using pulleys or by self carrying of loads.
· Use spectroscopic grade premixed He Ne gas with a 7:1 to 10:1 ratio (partial pressure/molar).
· This object copier machine has low maintenance but high initial cost.
· Information passed onto the Assembly line should be correct for this proper and efficient software like
- Far field technology provides advanced techniques for modeling scattered 2D and 3D data.
- Image ware surfacer allows you to manipulate point clouds and convert them into useful objects such as points, lines, planes
- Metris provides data preparation, registration, comparison, and reporting software for dimensional inspection.
- Okino polytrans does a great job of converting 3D models between formats.
- Paraform surface reconstruction software
- PRISM 3D software software for managing, sharing, and extracting information from as-built laser scan point clouds.
- UZR 3D Professional creates a 3D model from a series of object images.
· No wastage is there, since the materials that are not proper or unused are recycled.
· Pollution free.
· If there is any leakage of laser radiation, it can be detected by as a small bulb glows (red in colour) if any kind of damage occurs.
· The physical appearance of the machine is not given much importance as this is generally not manufactured to sell to many people… but the object which is replicated is sold.
We also researched on several formulae that is applied to this project.
1.If the density of the object is more the laser fails to penetrate through the object and is reflected back.. So as the density of the object increases the wavelength increases. This is proved by the following formula…
Energy (E) = mass* c*c {Einsteins energy mass equation}
Energy = h* u {Bohr’s dual nature}
C= velocity of light.
h = Plank’s constant.
Density = mass / volume
Using these formulas it can be proved that;
Density = h / (c* wavelength * volume)
Hence density is inversely proportional to wavelength. So if the object to be created is of higher density lower wavelength is to be used by laser source.
3. If the mass of the object increases then the speed of the belt on which the object moves decreases, so in order to maintain the speed energy has to be increased.
Subsequently the formula for this can be derived... and that is as shown below;
Density= ( h * velocity)/( distance *c *c)
Report on the overall development of the project!
1. During the second week of March we formed a team consisting of 8 members for the ENGINEERING DESIGN project. Initially we chose space travel as our topic… but later due to some relevant reasons it was changed over to OBJECT COPIER. All of us were really interested and eager to develop a machine for the same.
2. During the next week, the design of the project was decided upon. Here the main concepts used for the development was discussed upon. We chose to invent a machine that would replicate any given object ( considerable dimensions). For this we contacted seniors of MSRIT (M.Sc) who gave an idea for further development.
3. During the fourth week of March, Project design specifications for the project were made. These discussion were spread over a period of 2 days, in the first meeting overall PDS was prepared and in the second meeting many relevant information was further added and many correction were made.
4.During the first week of April, the concepts diagrams and the whole Machine were made…and the same was scanned and posted in the blog.
5. During the second week of April no much progress of the project was made due to internals.
6. In this week the detail working, construction, embodiment etc… for overall development of the project was made. Some corrections required in the PDS were also made.
