The design and development of G-code checker and cutting simulator for CNC turning operation
Bibliographic record
Abstract
CNC machines have been becoming popular in manufacturing sector for the last fourdecades. It still costs a lot of money to afford some aspects related to the operations of these machines, such as the hardware, the software and the brainware. One important aspect is the programming stage where this activity requires a skillful programmer and an appropriate programming media. To hire a good programmer is not a cheap and the best solution while having a commercial programming media is also not affordable for Small Medium Enterprises (SME) in Indonesia. This research was focusing on the design and development of a kind of program checker to see whether the program for a CNC turning machine is correct and ready to be fed to the machine. At once, this program was also capable of displaying cutting simulation of how the product to be cut in the machine. Therefore this program will help a small manufacturing company to avoid hiring an expensive expert or buying a special programming media. This program was specifically developed for a CNC Okuma Howa ACT 3 turning machine but it can be extended to other machine types. Some results were showed that the program can easily point out error location if there is a logical or syntax error in the NC program. Moreover, the simulation can be executed only if all errors have been corrected. This feature ensured that the simulation can run properly. To run the simulation, one has to set up some variables such as workpiece dimension, tool position with respect to the machine, cutter dimension and so on. Key words: CNC machine, turning operation, G-Code checker, cutting simulation.

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.
