Traditional hand-carving can no longer meet the needs of the development of the industry, so the emergence of engraving machines. Some defects in traditional hand-carving are very obvious, such as low efficiency, high production risk, material waste, and serious dependence on people's subjective consciousness. Machine engraving is gradually recognized by the industry due to its high efficiency, low risk, and material saving, which largely compensates for the defects of hand-carving.
People may say that the engraving machine is not perfect. For example, the application range of the engraving machine has been small for technical reasons. Some engravings must also rely on manual completion and lack of expressiveness. With the development of technology, the engraving depth of the engraving machine is deeper and deeper, the engraving precision is getting higher and higher, and the application range is more and more wide. The circular engraving and the stereoscopic engraving which could not be done before can now be completed by many machines. Even so, the machine carving also has its inadequacies, such as excessive dependence on technology, stereoscopic engraving is still insufficient, it is difficult to complete the engraving of irregularly shaped materials, once the engraving mistakes are difficult to recover, and so on.
The laser beam is transmitted and focused by the optical mechanism on the surface of the material, and the material of the high energy density laser beam action point rapidly vaporizes to form pit points. Using a computer controlled xy console to drive the laser head to move and control the laser switch as required, the image information processed by the software has been stored in the computer in some way. When the information is read from the computer in sequence, the laser head is along Scan tracks are scanned back and forth line by line from left to right and top to bottom. Whenever a "1" point is scanned, the laser is turned on and the laser is turned off when scanning to a "0" point. We know that the computer stores information in binary, which coincides with the two states of the laser switch. Therefore, the currently popular seal layout software can be used for special laser engraving equipment consisting of lasers, scanning tables, computers, and the like. Not only high precision, high speed, but also good results!
The biggest advantage of hand-carving is flexibility. Different engraving methods can be used according to different materials, and the engraving process can also be changed. The engraving machine is different. It needs to be designed and prepared before engraving. There is basically no room for modification after the start of construction. Especially the engraving procedure for different woods is basically the same. Only a slight adjustment can be made to match the machine with wood.
The biggest advantage of machine engraving is that it is easy to copy and maximize production efficiency. However, at the same time, this is the biggest disadvantage of machine engraving, that is, the work is easy to be similar. This requires the designer to constantly change the design ideas in order to have new styles and works.
Since there are no high or low points in different processes, why do people ask whether it is hand-carved or machine-carved? Why do people react differently when they hear machine carving? Do people have a soft spot for hand-carving? the answer is negative.
When people see a beautiful sculpture, what attracts them? Is it the production process of the sculpture? Obviously not, the artistic charm of the sculpture itself attracts them. Therefore, companies should be more concerned about how to enhance the value of art. And collectors are more concerned about the inner and spiritual enjoyment. In general, the artistic value of the engraving machine does not lie in itself, but rather its ability to create art and to maximize the popularity of art.
