·Preheating the driverless car to push the active safety device as standard
This year, BMW, Audi, Mercedes-Benz and other car companies have announced their own auto-driving completion schedule. Some well-known auto parts giants have even begun to test autonomous vehicles on Chinese roads. A lathe is used to fashion a rotating piece of raw metal, wood, or composite into a precise configuration using movable cutting tools, or bits set to varying depths. The process, known as turning, or machining, is most often accomplished with a horizontal lathe. Often, however, space or material constraints, sometimes even personal preferences, necessitate the use of a vertical lathe.

“Although many people think that the distance between autonomous driving and real life is still far away, in fact, many OEMs have planned to set active safety devices as standard products for automobiles starting from the second half of 2016.†November 6 Wang Zhan, global vice president of Delphi Electronics and Security, and president of Asia Pacific, told reporters that they have been very busy in the past two years. Almost all car OEMs are striving for active safety technology, and this technology is an important prerequisite for automatic driving.
Active safety will be written into the new CNCAP regulations. Unlike the driverless route chosen by Google, car companies generally believe that the market for autonomous driving is more promising. The only difference between autonomous driving and driverless driving is that the driver will always sit in the front seat of the car. This is the main reason why car companies are willing to bet on this path.
In the eyes of autobots, Google’s driverless plan is more like a conspiracy to subvert the auto industry. In order to prevent the sudden collapse of IT companies like Google on a certain day, first-line auto companies have been eager to make efforts since last year. Try to use autonomous driving to end Google’s dream ahead of time.
Therefore, active safety technology related to autonomous driving is becoming the darling of car companies. According to the survey released by Gasgoo.com, nearly 31% of the participants believe that the assembly ratio of active safety products of OEMs will be around 50%~80% in the next five years. Delphi, which has advantages in global automotive active safety technology, is now providing active safety application solutions to more and more OEMs, and the business has increased far more than expected.
"At present, the active safety assembly rate of some high-end cars is about 14%. We expect that the active safety market capacity of Chinese cars will increase by three times in the next five years, far exceeding other technologies." Wang Zhan believes that the speed of auto-driving and consumers The requirements for automotive safety performance will be the main reason why active safety technology is widely used in the future.
According to statistics, in the proportion of traffic accident categories, the rear-end accounted for 49%, the lane departure accounted for 27%, and among the death toll, pedestrians accounted for 31%. The results of the relevant European institutions show that as long as the driver takes measures 0.5 seconds ahead of the dangerous moment, about 50% of road-related accidents will be avoided. In order to win this precious time of 0.5 seconds, more and more car companies including Volkswagen, Mercedes-Benz, Volvo, Ford and Subaru have begun to introduce and load ESP, adaptive cruise system, off-road warning system, automatic emergency brake. Active safety technologies such as systems and parking assist systems.
According to Shen Junqiang, senior engineering manager of Delphi China Science and Technology R&D Center, some test requirements for active safety systems will be reflected in the new version of CNCAP next year, and the specific implementation time of this version may be in 2018. To this end, car companies, including Volvo and Cadillac, have added active safety configurations to the 2018 mass-produced models to suit China's national conditions.
In fact, in the new “2014~2017 EuroNCAP†new regulations introduced in Europe this year, the safety assistance project has been greatly strengthened, and vehicles without safety assistance systems will not be able to obtain a five-star rating. After 2016, active safety products for pedestrian automatic emergency braking will be officially listed as one of the evaluation indicators. Therefore, for major car companies, the development and deployment of active safety products has become an irreversible technological development direction.
Semi-automatic driving is the first to land. Now the automotive industry has reached a consensus that all the vehicles produced by the main engine factory must be equipped with active safety and entertainment system products, otherwise it will not be a mid- to high-end car, and will not even become a mid-range car in the future.
But this does not mean that all active safety technologies have the potential for mass production. Song Jian, a professor at the School of Automotive Studies at Tsinghua University, believes that this technology can only be universally applied if the price of the active safety aid system is controlled at 5% of the vehicle price.
"As far as I know, an automatic parking function now costs about 100,000 yuan. If the functions such as active collision avoidance and active steering are fully equipped, the price of a car may be unbearable for the average consumer. So active safety technology. The price, one day early, the technology can be popularized for a day," Song Jian said.
In fact, autonomous driving is not as simple as most people think. It is not a combination of advanced active safety technology into a new car. In fact, like unmanned driving, it requires the cooperation of many factors such as automobile manufacturing, government, and infrastructure to achieve it. Nowadays, the environmental roads in most cities still have technically unsolvable problems for fully autonomous driving.
At present, Bosch admits that its zero-collision is still difficult to achieve in a short period of time when it announces its predictive pedestrian protection system and product planning for building regional auxiliary systems. A simple example is that a predictive pedestrian protection system can capture pedestrians through stereo cameras and radars. This technology has been able to collect information from other vehicles blocking the line of sight.
However, for a single pedestrian, there are some situations that do not need to be stopped, only need to slow down to pass through smoothly, and for multiple pedestrians, deceleration and braking can be used flexibly to avoid collision, and there is still autonomous driving technology. barrier.
"Although autonomous driving is the future development trend, in the next two or three years, the protagonist of automotive products is not self-driving, but semi-automatic driving." Wang Zhan believes that when active safety and automotive intelligence and other technologies break through the cost bottleneck, Large-scale mass production is just around the corner, with the possibility of semi-automatic driving with interventions being the most likely, which makes some of the smarter and active safety technologies more practical as a staged mass production goal.
Essentially a horizontal lathe turned on end, a vertical lathe, also called a boring tool, is composed of basically the same parts as a horizontal lathe. As implied, the functions of vertical lathes are performed up and down, rather than side to side, as is the case with horizontal lathes. This vertical alignment allows short, heavy, bulky materials to be machined more efficiently than with a horizontal lathe.
All lathes, vertical or horizontal, are comprised of the same basic parts. The headstock encloses the spindle and chuck, the parts that actually turn the material. The bed catches the shavings, and also serves as a brace for the horizontal lathe. The feedscrew and leadscrew, mounted on the lathe carriage, adjust the speed and distance traveled by the cutters along the stock. The cross slide and compound rest position the toolbox, which, in turn, mounts the bits.
The tailpost, at the opposite end of the lathe spindle, clutches the stock and braces it, thus eliminating wobble and vibration. The headstock and tailpost may be at the upper or lower end of a vertical lathe, or to the right or left end of a horizontal lathe. Either way, the headstock is one end of the lathe, the tailstock, the other.
Vertical lathes may be vertical turret lathes (VTL), where a turret holds various toolboxes, allowing little wasted time resetting bits during the machining process. There are also computer numerical control (CNC) vertical lathes in which the entire machining process is computer operated.
The top of the lathe pyramid are the CNC vertical turret lathe machines, most often used to turn stainless steel into precision parts for engines, turbines, transmissions, etc. These machines, though expensive to purchase and operate, are perfectly suited to the task, saving space, as well as over-stressed equipment. A CNC VTL can also be used on alloys to efficiently turn precision bearings and gears.
A vertical lathe can used on rough wood in a home workshop, mainly for its space-saving attribute. Many home hobbyists, however, simply feel more comfortable turning wood up and down, rather than side to side. Altogether, the vertical lathe is a very capable and versatile tool.
