1, the starter training is not in place, and the starter operation procedures are not done as required. 2. There are many abnormalities in the equipment, and the laser energy is unstable, which leads to the cutting efficiency not reaching the UPH value. 3. Not all the 20 devices are enabled, and the laser fault is serious (9 # 14 # 19 #). 10W laser cutting efficiency is low, so it is not enabled. 4. The time for making the first article is seriously overtime every time it is turned on. (about 2 hours) 5. When the equipment breaks down, it takes a long time to deal with the failure 6, and the production line replacement time 7. The cutting parameters of the equipment are often adjusted by employees, and the cutting time is extended by 2-3 minutes. It takes a long time to adjust the cutting parameters when changing lines, and the cutting parameters of each material are not recorded correctly.
