About Encoder Accuracy
There are many factors that affect fastener location accuracy. Some of the common factors are bit or socket extension wiggle, tool spindle compliance and spring loaded spindle collapse, component dimensional consistency, accuracy of the component location in the fixture, and of course, repeatability and accuracy of the smart-arm encoders. These factors are not usually critical unless the fastener locations are very close together (almost touching).
When all of the physical location issues are optimized, then typically your controls should be able to read our encoder outputs to differentiate between fasteners within approximately 1/8” (3mm).
