Technology in the Manufacturing Sector - Assignment Example

Eli Whitney created these machines to help in large scale manufacturing in the assembling area. Processing machines help in expelling metal with a spinning cutting apparatus known as processing cutter. The machine has a few connections, and the machine can be utilized as a part of the exhausting, opening, roundabout processing among different capacities. The machine is likewise valuable in cutting keyways, racks and design, and fluting taps and reamers (Yüksel, et al., 2017). The machines are typically delegated either vertical or even to show the pivot of the processing machine.

The vast majority of these machines have independent electric drive engines and coolant frameworks. This Computer Numerical Control (CNC) milling is one of the most common forms of CNC Machine. It is capable of performing the functions of drilling and often turning. CNC mills are useful and normally classified as per the number of axes that they have. They have axes which are labelled. The machines are usually programmed automatically using different commands like G-codes and M-codes. The G-codes and M-codes usually represent specific CNC functions in alphanumerical format.

They are instrumental in modern manufacturing as they improve the manufacturing design process (Kibbe et al., 2014). The new technology involves the combination of the CNC and CAD machines in the manufacturing process. The two machines are interfaced, and it requires a more skilled operator to manage it. The technology designs in stages with CAD tool being used first before it is switched to CAM tool. The new technology is useful in modern manufacturing and helps produce useful and desired objects (Kibbe et al., 2014). With parametric technology in place, it can define the dimensions relations among parameters and between design parts.

From the diagram above, we can define a new part by assigning new values to the parameters. Other characteristics of modelling the user access and expression can be expressed in the 2-D and 3-D.

The model above gives the geometric estimation or the prototype design of the object. Figure 3:surface grid generation Figure 4: Synthesized surface grid generation 3.0 Discussion From the analysis of the CAD/CAM system prototype above, it shows that the computer controlled machine operation is done using the program which specifically follow the tool-path and is programmed using the two machine languages. This help in defining the tool path during the operation of the machine. It is clear from the above diagrams that the tool is purely moving along defined paths.

The paths which it follows is shown in the diagram below:- From the path being followed. It starts with the work piece geometry and free form surface selection. Figure 1 and 2 shows this arrangement and the surface selection for the new design which is being modeled for the prototyping. Choosing the free surface form gives the overall design on where it will work and perform other operations of the design. The second step is surface grid generation for part of machine of the total surface. The generation of grid is shown in figure 3 and 4 giving the overall object piece outlook for the design.

In performing the operation it also depends on the accuracy of the feed rate and other specification of the machine, for CAM operation CNC machine is used. The third part is the determination of cutting depth in axial and radial directions in part of the total geometry. The curvature tool path effect on the thickness as well as the exit and entry are analyzed in the diagram and the cutting force model of the linear milling process which is then corrected. The calculation of maximum cutting force is being done at this stage and this help in designing the object and it has direct effect on the cutting tool.

The images of the object piece is shown in other pictures above with clear specifications. In order to ensure the success of the CAD system implementation, more training is necessary and this will help the operators to get well equipped with necessary skills for the operation of the machine. The machine work is closely monitored and analyzed for the desired surface profile for the production of the smooth surface. The use of computer programming is based on control avoids any kind of disruption in the process.

Using different tools in coming up with the final project is equally important as it will help in coming up with the desired shape of the tool being modelled. Another important factor which should be considered in the process is the cost factor as the design should take the cheapest approach in coming up with the model. 4.0 Conclusion This paper gives a brief insights on the optimized process analysis for producing a freeform surface using the 3-axis CNC machine, CAD and CAM machine analysis.

The design analysis is done using the CAD based 3D surface model. From the design, there is a consensus that the overall increase in the automated design tool in manufacturing sector is undeniable. CNC mills are useful and normally classified as per the number of axes that they have. They have axes which are labeled. The machines are usually programmed automatically using different commands like G-codes and M-codes. The G-codes and M-codes usually represent specific CNC functions in alphanumerical format.

This is another important aspect of this project as it help in ensuring that the design is accurate and to the desired output. The advantage of using these machine is that they reduce labour cost by giving a more accurate component in manufacturing process. It further help in reducing the total production lead time as it makes it possible to see how the component will be reduced in the manufacturing process. The machine help in reducing the tool load and provides high speed machining process.
