Coordinate measuring machine, in fact, can be divided into three types which are automatic, semi-automatic and manual. Automatic is completely controlled by computer, while manual is completely controlled by hand. The semi-automatic does not have a fully automatic probe rotation and control system, so as long as the stylus angle needs to be changed, the probe angle must be manually changed. Let's learn the difference between semi-automatic and fully automatic.
1. Price
From the buyer's point of view, the first concern should be the price difference, the probe of the semi-automatic coordinate measuring machine and the probe of the fully automatic coordinate measuring machine are different. Manual is cheaper than automatic.
2. Measuring Accuracy
Relative to the price, the measurement accuracy is one of the guarantees to test whether the product is qualified, so the higher the accuracy, the better the quality. Semi-automatic, due to the need to manually adjust and test, there may be a certain error in the measurement process. Fully automatic by PC control, greatly reducing human error. Therefore, relatively speaking, the accuracy of automatic coordinate measuring machine is higher than that of semi-automatic coordinate measuring machine.
3. Producing Efficiency
The efficiency is very import for an enterprise. The automatic coordinate measuring machine is controlled by the computer during the measurement process, and only the engineer needs to set and input the program in front of the computer. A semi-automatic coordinate measuring machine is not possible because it has to be tested manually. Because of the need to manually change the probe, semi-automatic coordinate measuring machines have advantages over automatic coordinate measuring machines.
We have described above the difference between semi-automatic and fully automatic CMM. In fact, it is not possible to say which is better, because the choice of fully automatic and semi-automatic depends entirely on the actual situation. We cannot generalize.
