The machine design is a creative work. engineer not only ve the he work, but also must in aspect and on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manuf

Therefore, designs nel to have to have to have the because spends the time and the endeavor certainly cannot guarantee sfully. A brand-new design, the re

This certainly is not an easy work, certainly does ve to all people to say in fact all is the most superior area and the operatingAnother important question, project engineer must be able to carry on exchange and the ion with other nel. In the initial designs nel to have to carry o

Sometimes, when in front of sembly or the packing foreign shipment experiment only then he design some of flaw. These exactly showed the design is a

Always a better method to complete the design work, designs unceasinglydiligently,seeksthesebetternel to be Recent year, the engineerig material choice already appeared importantly. addition, the again appraisal pro materials can obtas should be to the material continuously the s. The ne
20、w material unceasingly appears, but some sibly can reduce. The environmental material recycling aspect and so on use, workers nd security frequently attach the new limiting condition to the choice of material. In order to reduce weight or saves the sibly can request the use different material. from
21、domestic ernational competition, to product service convenience request enhancement and customers aspect the and so on re, can urge the people to carry on to the material reappraises. Because material does not select when created the product responsibility lawsuit, has had the profound influence. In
22、 addition, the material and n the pro sing erdependence is already known by the people clearly. Therefore, in order to can and guarantees the quality in the reasonable cost under the premise to obtain satisfaction the result, project engineer makes engineers all to have carefully to choose,thedeterm
23、inationand theuseMakes any product step of work all is designs. Designs usually o several explicit stages: (a) preliminary design; (b) functional design; production design. In the preliminary design stage, the designer considered the product should have function. Usually must conceive and consider s
24、everal plans, then decided thiskind ofthought iswhether feasible; If isfeasible, thenshould makes the further improvement to or several his stage, the which only must consider about the choice of material is: Whether has performance to conform to the request material to sible to supply the choice; n

26、new In the functional design and the engineering design stage, needs to make practical feasible design. Must draw up the quite complete in this chooses and ach kind of componentsthe material. Usually must makeprototype or the working , and carries on the experiment to it, the product function, the r

28、efully considers the product the outward appearance, the cost and the reliability. Has the achievement very much the company when manufacture all prototypes, selects the material should the material which with its production in be same, and uses the similar manufacture technology as far sible. Like
29、this has the advantage very complete prototype if cannot act according to economically to make, or is prototypical and the to the company. The ipated sales l production s the quality and the reliable aspect is very y different, then this kind of does not have the great value. Project engineer is bes
