The positioning accuracy of laser photoplotters will be affected by machine accuracy, software errors, metric errors, environmental influences, and measurement errors. So how to improve the positioning accuracy of the laser photoplotter?
1, laser photoplotter software calculation error
Software errors can be divided into calculation errors and quantization errors, which are errors caused by calculation accuracy. If the accuracy of the ordinary floating-point operation is too low in the calculation, the calculation error will be caused; however, the double-precision operation is generally used in the calculation, and the precision is sufficient, and the calculation error is not caused.
2, laser photoplotter machine precision
Laser light painting machine accuracy is technically demanding. The main influencing factors are: structural design, machining accuracy, assembly accuracy, material deformation, and theoretical error.
3, laser photoplotter compatibility error
The photoplotter is designed to be metric or imperial. Metric machines produce errors when processing imperial documents; imperial machines also produce errors when dealing with metric documents. However, its impact is negligible.
4, laser photoplotter measurement error
In theory, there will be errors in the measurement, so it is necessary to pay attention to the quantifiable method when measuring. The accuracy of the measurement tool should be high, and the influence of various factors should be excluded as much as possible. Only when the method used is correct can the impact of various factors be reduced.
