ps11Month's subscription is out!11Click-through rate is x2=12000 clicks,Of course, this 200 is the average value!But the manuscript fee is 15.23 yuan,Plus the previous 5.7 yuan,There are still ten months before the manuscript fee is issued! Co-authored after everyone clicks,After watching the piracy,Okay,From next week,Release anti-piracy chapters,Nima is too tricky, the author thought it was very good,12000 clicks,The author has at least 5,000 manuscript fees!But hehe,30 times the difference,You know! The starting point of the coin income is half of the author's! That is to say, the author's manuscript fee in November is 30.46 yuan,Ah! If you don't publish it, it's not good.,The current piracy is too rampant, okay。 There is no way, do you want the author to point to the full attendance award every day? Thank you for the book friends who have spent the money! Now the author is doubting whether there are any pirated websites in these manuscript fees. Okay, let's talk to the editor on Monday, and let's prevent piracy directly! This data is too hurtful, okay.

After Kim Myung-ho didn't let Pete say this, Kim Myung-ho asked Pete to say something simple, but Kim Myung-ho didn't expect Pete to start saying a lot of things again.

Rapid prototyping technology is an advanced forming manufacturing technology developed in the mid-80s of the 20th century, which quickly obtains the prototype of mechanical parts through the integration of high and new technologies such as computers, numerical controls, lasers and materials.

As an indispensable and important part of new product development, rapid prototyping technology directly affects the new product development cycle and development cost. At present, there are two main types of rapid prototyping technology: stacking forming and removal forming. Stack molding is a method in which materials are added in a certain order to create prototypes, and its typical representative is rapid prototyping technologies such as FDM. It can quickly manufacture 3D prototypes or parts with arbitrary complex shapes and certain functions directly from the CAD model without the need for tools or molds, but there are also problems such as limited types of materials to be selected, small size of parts that can be manufactured, poor surface quality and low precision. The removal molding method is to manufacture prototypes by separating part of the material of the substrate, and its typical representatives are CNC machining such as turning, milling, wire cutting, and EDM. It has the advantages of many types of optional materials, large size of manufacturable parts, good surface quality and high precision, but there are also problems such as limited shape and structure that can be directly processed and manufactured, and tooling fixtures that need to be assisted.

Since the beginning of the 60s of the 20th century, the United States has successfully developed two kinds of industrial robots and applied them in industrial production. Since it began to be applied in the automotive industry in the 70s of the 20th century, it has been increasingly applied in other manufacturing industries. However, most of them are used for simple and repetitive heavy work, such as loading, unloading, handling, etc., as well as places with harsh working environments, such as painting, welding, sand removal and cleaning of nuclear waste. After the 90s of the 20th century, due to the open chain structure of industrial robots, it can achieve flexible manufacturing and adapt to the production of multiple varieties and small batches, and the production of multiple varieties and small batches is the characteristics and application scope of rapid prototyping technology, which promotes the application of industrial robots in rapid prototyping technology.

Rapid manufacturing prototyping technology is to obtain the combination information about the geometry, structure and materials of the prototype and parts with computer-aided design or entity reverse engineering, so as to obtain the concept of the target prototype and establish a mathematical description of the prototype, and then input this information into the computer-controlled electromechanical integrated manufacturing system, through point-by-point, face-by-side molding of materials, and then after necessary post-processing, so that it can meet the design requirements in terms of appearance, strength and performance. This makes it possible to manufacture prototypes or actual parts quickly and accurately. Over the past decade, researchers have built a variety of robotic rapid prototyping systems in order to shorten product development time, improve the functionality of equipment, and improve environmental harmony and product quality. In 1996, a system of engraving robots was proposed. The system includes an industrial robot and a workbench, it is a rapid prototyping system based on milling foam materials, mainly to provide designers with a reference for further design, the size of the prototype is about 80cm, the accuracy is generally 0.5~2mm, and it takes about a few hours.

A rapid prototyping system based on industrial robots is generally composed of a computer, a robot, a control cabinet, a workbench and a processing tool, as shown in Figure 3. The research results mentioned above, whether it is a prototype system of material stacking molding or material removal molding, are based on the CAD model of the part, generate a CAM multi-axis machining trajectory that conforms to the characteristics of the robot trajectory, and convert the CAM machining path into a robot machining path through self-developed software for data conversion. The focus is on how to generate efficient toolpath paths and improve machining accuracy to overcome the inherent shortcomings of rapid prototyping systems. Compared with traditional rapid prototyping systems (RP processing equipment) for material stacking and molding, as well as NC machine tools, the rapid prototyping system for industrial robots has its own advantages:

(1) In kinematics, industrial robots have flexible arms and multiple degrees of freedom, which are more degrees of freedom than general three-axis machine tools and five-axis machine tools, and can theoretically process parts of any complex shape;

(2) Compared with NC machine tools, the robot can save 40% of the space for the same working area, and has a price advantage;

(3) Many existing common materials (such as wax, wood, foam and some other lightweight materials) can be used for processing, and the processing of these materials does not cause vibration of the robot system. Whereas, RP processing equipment can only process certain materials. Rapid manufacturing prototyping technology is a leap forward in advanced manufacturing technology, which proposes a new mode of thinking from the forming principle and creates a new opportunity for the development of manufacturing technology. With the deepening of the research of rapid prototyping technology, people are constantly exploring new molding methods and developing new molding materials while improving its accuracy and reliability. Rapid manufacturing prototyping technology based on industrial robots is a complex task, considering not only the complex shape of the part, but also the characteristics of different materials, as well as the selection of machining tools. The main problems faced are the accuracy of the processed prototypes, the limited variety of materials and the mechanical properties. With the rapid development of rapid manufacturing prototyping technology and industrial robot technology, especially the development of industrial robot technology, such as the improvement of the repeated positioning accuracy and load capacity of industrial robot end effectors, it will inevitably lead to the more and more extensive application of industrial robots in rapid prototyping technology.

Okay, Kim Myung-ho didn't let Pete tell him about car manufacturing, but Pete talked about robots, okay, this is a big set. Kim Myung-ho was completely stunned.
