to the motor. For example, transmit the number of pulses which can make servo motor
run a circle, and then measure the distance between the two points by the
interferometer. It’s ok to fill the ted number of pulses and the distance in the platform
configuration tool.
The method of sending a fixed number of pulses in CypCut is to open the "File" -
"Diagnosis", select shaft as shown in the following figure window, input the pulse
number, and click "Send."
6.7.4 Error measurement
The error is measured by the interferometer, commonly known as "Open
interferometer." Generally, control the machine to stay for some time at an interval
distance by the numerical control system, and then laser interferometer can measure
the actual position of each point. The correspondence table of the theoretical position
and the actual position can be obtained after all location measurement has been
completed.
Most of the laser interferometers, such as Renishaw, must first set travel range,
test interval and time spent at each point before starting the test, for example, stay one
second every interval 30 mm. Laser interferometer decides whether to be measured by
determining the separation distance and dwell time.
Firstly, determine several parameters:
Travel range. The total travel range of preliminary measurement, generally is set
slightly smaller than the stroke of the machine design.
Measurement interval. Theoretically, the smaller the measurement interval is, the
more accurate the results is after the compensation; but the smaller the measurement
interval is, the more the point required to be measured is, and also the longer time it
takes. Recommended interval value is between 10 mm to 100 mm.
Dwell time. The minimum dwell time of Renishaw default is two seconds.
Opens CypCut- "Numerical Control" - "light path adjustment" screen, and find
