Optimization of the multi-spindle drilling stage at TC Industries Inc. during grader blade profile changes : final report
Bibliographic record
Abstract
This report outlines a design that can be integrated into the multi-spindle gang drill operation at TC Industries Inc. in Selkirk, Manitoba. This design will improve the current process of changing the different fixtures that are unique for each blade profile. The problem with the present system is that poor production exists in the multi-spindle drilling stage during grader blade profile changes. Specifically, the backstop blocks take a long time to change and require manual shimming before production can continue. The proposed design outlines a device that is able to rotate about the horizontal axis which provides four places for modified backstop blocks. Parallel to the bits on the multi-spindle gang drill will be a safety cage that splits the area so that the machine does not need to be locked out when an operator appropriately revolves the die rotor to get the proper backstop block in place for the next order. For blade length changes, a sliding mechanism will allow the rotor to move down the length of the drill. The new workpiece fixture is illustrated in sufficient detail so that further development can be made by TC Industries Inc. prior to a trial implementation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
