Dataset for Orthogonal Cutting Simulations of Ti-6Al-4V Alloy Based on a Tanh-Modified Johnson–Cook Constitutive Model

This dataset accompanies the manuscript “Interpretable serrated-chip morphology quantification for identifying strain-rate sensitivity in Ti-6Al-4V cutting simulations.” It contains processed parameter data and simulation-derived observables obtained from Ti-6Al-4V cutting simulations based on a tanh-modified Johnson–Cook model. The strain-rate sensitivity coefficient C was treated as the target parameter, while the thermal-softening exponent m and the effective failure-strain scaling variable epsilon_f were treated as non-target perturbation variables. The deposit includes processed morphology and force descriptors, manual reference measurements for descriptor validation, figure source data, and portable Python scripts for cross-validation, feature ablation, perturbation-group holdout analysis, and constitutive-curve plotting. The morphology descriptors comprise Hc, w, theta, P, and Gs, while the force observables comprise the steady-state mean resultant force Fm and the peak-to-valley force range DeltaF. Large raw finite-element simulation outputs and non-essential detector-training artifacts are not included because of their file size and project-specific dependencies. The deposited files are intended to support verification and reuse of the processed-data analyses reported in the associated manuscript. File definitions and usage instructions are provided in the README and metadata files.
