"China Aluminum Network" "I believe that no other company can make this kind of styling." To put out such strong words is Sony's consumer product and service department's personal video and audio business headquarters's core technology department and agency design department's machinery. Engineer Shi Qiaoxiu.
Stone Bridge's work is based on the designer's proposal to design, until the actual mass production. It is the digital camera “Cyber ​​Shot DSC-TX66†that allows the technicians who reflect the design to be reflected in the actual product to speak out. This includes a variety of advanced manufacturing technologies.
When you see the TX-66 in a shop with a large number of pocket digital cameras, you will undoubtedly feel that this camera is very outstanding. The big difference from other products is its "edge", sharp corners are its big bright spots. The front surface of the TX-66 is full of curved surfaces and has some bulges. The surrounding area is like a direct cut. Connecting the soft surface with the vertical side is a very conspicuous corner. The body showed the compactness of using the metal side bread to live in rich contents.
In fact, the DSS-RX100, the higher-end model of the CyberShot series, has adopted the same concept in its modeling. The product's design goal is also to give people the same delicate and weighted impression as cutting out on a rectangular block of aluminum. In this regard, the head of the four divisions of the Sony Digital Imaging Business Unit headquarter of the Sony Digital Imaging Business Unit responsible for the design of the RX-100 organization Sasaki Sasaki believes that the key lies in the fineness and level of the corner R from the side that stands upright to the horizontal plane. Smoothness."
However, although it is required to give the impression of cutting aluminum blocks, it is not really possible to make the housing by cutting blocks of material. In the two feasible solutions, the one that succeeded in punching the sheet into a certain shape and then thinning one of the faces was a manufacturing solution.
After the TX-66 is punched out of the overall shape by deep-drawing processing, the TX-66 is machined and hand-worked around the side surface that supports the bulging surface. On the other hand, the RX-100 is made by deep-drawing a sheet with a thickness of only about 1 mm into a certain shape, and then evenly and smoothly thins the upper plane of the body by about 0.5 mm. In deep-drawing processing and cutting processing, as long as the size is slightly deviated, it will be a work that needs to be done with caution.
Although the processing effect is only as thin as a planer once, but it will have a very big impact on the design. The two engineers said in unison that if the deep-drawing process was performed, the angularity was not sharp enough to show the precision after cutting. The example of the design of these two models shows that the micro-processing of the corner R has a very big influence on the design.
After understanding the details of the design process that determines the pros and cons of the design, it is necessary to consider the balance between design and production efficiency in the design. Considering the manufacturing process on the basis of understanding various conditions such as the design of molding, processing procedures, and cost, it is the requirements put forward by designers in this era.
At present, the combination of stamping and aluminum cutting is no longer a rare method. For example, the Unibody construction used for the MacBook series and the iPad, etc. formed by cutting the entire thick plate is an application example of this processing combination.
However, although Sony and Apple's technology use the same processing method, the method and purpose are completely different.
Sasaki Kumi, chief of the CyberShot development team, said, “We have 6 years of combined machining experience in stamping and cutting.†What the team pursues in this process is to meet the changing demands of consumers at all times, perform the required processing with less equipment, increase the production efficiency, and avoid the high-efficiency product manufacturing concepts of investment and material waste. This is also a rapid styling development approach that can meet changing consumer preferences and trends.
Moreover, this development approach also means that the new processing technology and experience gained in it can be immediately applied to the next attractive design while production continues. For example, to hide different metal texture lines on the sliding panel of the TX-66 lens. According to reports, this is achieved through the use of multicolor aluminum-tolerant technology, and is also based on the design proposed by the technical staff.
The product manufacturing policy of Apple is that it takes a long time to seriously design a few products until it is approved. At present, this method has achieved great success, but the imitation of Apple's design method is meaningless. It would be better to delve deeper into the methods that the CyberShot development team used to design a variety of products at a faster pace of development. This will be a great weapon for participating in global competition.
The current top priority is to build an environment where the collective design experience of technical personnel can be sublimated into the collective wisdom of the company. How to apply this technology on digital cameras to other product areas? This may be the key to improving the overall value of Sony.
