CNC machining precision is very high also need locksmith? Many people ask. Small make up also not quite understand, sought advice dongguan to open cheng precision hardware limited company ability to understand designously.
CNC precision greatly improved, the original locksmith function has been greatly stripped.
The locksmith functions are divided into several categories:
1. When the machining precision of the machine tool is insufficient, the assembly precision I shall be achieved through the research and matching of the fitter. This function is due to the improvement of CNC machining equipment precision, this part of the locksmith's function has become lower and lower, especially in Europe and the United States and other developed countries, has this part of the work is likely to be removed from the locksmith.
2. For the assembly of the mold, the work shall be carried out by a fitter and cannot be replaced.
3. Mold modification, adjustment, disassembly, etc., shall also be carried out by the fitter.
In a broad sense, the fitter needs to have a very good manual work, can be all kinds of processing parts through manual grinding and matching to meet the needs of the machine and other equipment, since the improvement of CNC machining accuracy, this kind of fitter function has been increasingly weakened, now most of the fitter is just assembly workers.
Kaicheng precision hardware believes that the progress of technology will eliminate a lot of manual work, but it is impossible to replace all people.
Yuezhengjia makes three points for discussion.
1. Minimum step size problem: there is a minimum step size in any machine, which will deviate greatly from the ideal model. And people can be repeated grinding, relative to the machine is very easy to solve.
2. Degree of freedom (DOF) and kinematics:
A human hand has 25 degrees of freedom (not counting arms) to outdo a machine, which is why it is more flexible than a machine.
The motion of the machine is controlled by the dynamic model, while for people, it seems that no one needs to set up an equation before moving. The machine (such as the manipulator) adjusts the posture to need to use the posture transformation matrix unceasingly, to the posture equation unceasingly positive solution, the inverse solution. The hand is a real-time feedback sensor, can be real-time, constantly, without computing to adjust posture.
3. The control ability of the machine for output force is lower than the control ability of the human brain nervous system for movement, plus the difference between visual and tactile feedback and processing.
