Maintaining TCP Accuracy
TCP isn’t a “set it and forget it” setting. It can drift over time due to tool wear or replacement, flange deformation after a collision, thermal expansion, or changes made by operators. To maintain accuracy, high-precision tools should be recalibrated weekly or monthly. Develop a checklist-based routine for daily pre-run TCP verification, and use automated diagnostic routines if your robot controller supports them.
Before every shift, confirm that the tool is securely mounted and that your reference object is present and correctly placed. Check whether the TCP appears consistent across repeated motions. Log the date of the last successful calibration, and always recalibrate after tool changes or unexpected impacts. Consistent logging and procedural discipline help ensure lasting precision.
You can also define backup TCP configurations for tools that are exchanged frequently. This allows fast recovery and consistent performance across different applications and robot programs.
