Design and Evaluation of a Pneumatic Gantry Robot for the Grinding of Steel Blanks
Bibliographic record
Abstract
This paper describes the design and evaluation of a pneumatic gantry robot that is used to grind the edges of steel blanks as part of a finishing operation prior to being stamped. The objective of this research project is to automate the grinding process in order to reduce the frequency of cracking. The required force and degree of precision needed were thought to be within the capabilities of a pneumatically actuated robot. This would keep the cost of the apparatus down, which was important given the low capital cost of the manual operation. Furthermore, given that manipulation of the air pressure is the mechanism used to move a pneumatic actuator, the combined control of force and position is inherent to the system. A number of different pneumatic circuit configurations were examined before adopting a design that uses a combination of directional solenoid and flow control valves controlled by a Programmable Logic Controller (PLC). Pressure transducers and analog linear potentiometers are used for data acquisition. Laboratory test results are presented as well as a discussion of additional work that must be completed with the pneumatic gantry robot before field tests are conducted.

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.
