Methods, apparatus, and computer program produ cts are provided for managing tools and calibrating tools when performing assembly instructions in a computer directed assembly system. To ensure tools remain calibrated, in one embodiment a tool identifier associated with a tool required for the assembly instruction is obtained. Using the tool identifier, a tool usage time for the tool is aggregated from an assembly reco rd database. To determine whether the tool may need calibration, the tool usage time from a last calibration point is compared with a tool usage threshold for calibrating the tool as provided for by the associated assembly instruction. If the tool usage threshold is exceeded, using the tool is disallowed unless the tool is recalibrated. Alternatively, the tool is authorized for use to perform the assembly instruction when it is determined that the tool usage time from the last calibration point does not exceed the tool usage threshold. |
