Key factors in machine design

Shops looking for a milling, turning, or multitasking machine want the best system for their money. They also want machines that can handle their applications. But beyond these are several other important considerations, some general and some specific to each machine type. So it is imperative for machine designers to consider several important factors while doing machine design. Cost has always been the major factor of consideration while designing the machine elements or machine and in this age of competition it has become more important. The best machine design is the one, which help get the finished product with all the major functionalities and highest possible quality at the lowest possible cost. Gone are the days when expensive and bulky materials were used for making the machine elements. Earlier machines used to be very heavy and consume lots of power. Now the trend is high output and efficiency. Full functional machines consuming low power and giving high output in terms of the number of the products manufactured. Some computer controlled machines can manufacture the components very fast and are highly efficient. The machine's elements should be strong enough to sustain all the forces it is designed for so that it is not damaged or permanently deformed during its life time. The machine designer should consider the force, the machine can be applied to and consider all the relevant factors that could affect its life. The machine should be rigid enough so that under the effect of applied forces for which it is designed, there is no deformation of the machine or machine elements beyond the specified limits. If there is excessive deformation, there are chances of failure of the machine elements and the whole machine. Wear is the removal of the material from the metallic surface when two surfaces rub with each other. If there is more removal of the material, the component will become weaker and eventually break. The effect of wear can also be reduced by increasing the surface, so that during the lifetime of the mating machine elements they will not fail even if there is some wearing between them. Lubrication between the two mating surfaces of the elements of the machine helps reduce friction between them and wearing of the two surfaces. Thus, it prolongs the life of the components of the machine. For the safety of the machine operator, hazard producing things from the machine should be eliminated and the design should confirm to the safety codes. Factors that govern machine design In a shaky economy, design for costing, works by setting a target cost from the start, and focusing innovation on meeting this cost goal without exception. Price is typically the first thing shops examine. However, any financial evaluation should consider the long-term cost of a machine and not just the initial sticker price. Some industry experts say that cost is not the best approach to machine design because focusing on cost alone can sacrifice other important opportunities for innovation. Three factors govern machine design and development: speed, quality and cost. Speed is the time it takes to bring a machine to market and see a return on investment. Quality relates to the user's impression of a product and includes features, reliability, and performance. Cost is the amount needed to develop and make the machine, and it's usually defined up front. It's the design engineer's job to balance these three factors. Often, cost to the buyer is not what makes the machine innovative. Rather, the claim to fame lies in being first to market or having unique features. It is usually possible to satisfy requirements for two factors, meaning something must be sacrificed. Sometimes that is cost. It is important to look at all the factors involved to decide what is most important. Focusing on only one area can result in meaningless innovation. In today's market, yoNIKE AIR JORDAN
