Mechatronics & Robotics · Last updated: July 30, 2026 · How this entry was written
Definition: The Tool Center Point (TCP) is the precise coordinate on a robot end effector, such as the tip of a welding torch, that the robot controller references for position and orientation. It defines the effective point of operation for tool interaction with the workpiece.
Example in context
“During the robotic welding setup, the engineer precisely defined the TCP by touching the tip to a reference point.”
“Robotik kaynak kurulumu sırasında mühendis, ucu bir referans noktasına dokundurarak TCP'yi hassas bir şekilde tanımladı.”
Where engineers use it
The TCP is defined in the robot controller during initial setup and whenever the tool is changed. Engineers use it to ensure accurate path execution relative to the workpiece.
Synonyms: TCP, tool frame origin
Practice: can you use “Tool Center Point” at work?
A trainee is programming a robot to apply sealant. They must define the TCP using a single-point calibration method, but the tip is slightly bent. How should they proceed?
