Acuity Sensor Test Fixture
SolidWorks Rendering
This fixture needed to be designed to test the rotational repeatability of a theta motion stage (see Force Gauge Test Fixture for another fixture that tested this part).
Project Summary and Design Steps:
Designed a base plate in SolidWorks to be compatible with the available acuity sensor
Created and dimensioned a drawing of the plate part with DFM principles
Chose of the shelf parts and assembled the fixture on SolidWorks to confirm dimensions before physically assembling the fixture
Developed a python code to enable the sensor to pick up data at the right rate and in the right units
Troubleshooting and Results:
Had to try a few versions of the code because it would read a nonsense value if the sensor was out of range
Also had to increase the precision of the values the code produced because the part rotated in very small increments
Figured out how to add a marker flag to the part being tested so that it could be sensed
Designed and 3D a printed chip holder to attach this flag to
Tested the acuity sensor program on an existing machine to ensure that the code worked properly
