The industrial design originated in Germany and was founded by Hermann Modayius. The "German Work Union" (October 6, 1907) was opened at the 1st annual conference by the architect Todd Fiscia. He said, "Between tools and machines, there is no high standard of work with established boundaries. Only by relying on tools and relying on machines can we create. Once people have mastered the machine, then the tools can serve us as they please. "Fisher also further stressed: "mass production, separation, is not a dangerous thing. Industry, if lost in the direction of making high-quality products, is to forget all members of the community, is cynical, this It is the most dangerous." But the problem has not been solved. Good design does not have to rely on craftsmanship to produce, machine production is unlikely to produce good design. Modayis said that this is beyond reproach.
In China, mechanical products account for 70% to 80% of single-piece and small-volume products. These products are generally processed by general-purpose machine tools. When the product is modified, the equipment can be adjusted to a large range, especially by curve and surface. Bonding performance index Unmodified UF butanol modified LF shear strength (MPa) Water immersion 24h Shear strength (MPa) There are cracks without cracks for 4 weeks.

Nanjing: Jiangsu can be seen from the above two tables The performance of the urea-formaldehyde resin modified by butanol is far superior to that of the unmodified urea-formaldehyde resin. The author believes that the application prospect of the modified resin will be extremely broad. â–¡ 1 Luo Hesheng. Plastic Handbook.

Research on free formaldehyde in urea-formaldehyde resin modified by decyl alcohol for casting.
Complex parts composed of enterprise technology development contours can only be processed by means of master and imitation machine tools, or by hand-operated methods by means of scribing and template. Machining accuracy and production efficiency are greatly limited. 4 Conclusions can be seen from the above examples. The CNC machine tool simplifies the machining process, making it easy to machine on a conventional machine tool.
Therefore, the product is more considering the beauty of its design. It has become the requirement of the times to pay attention to the design of the style, improve the form beauty of the product, ensure the quality, improve the efficiency, and the enterprise can stand in the invincible position in the competition.
