Tool–Chip Contact Length

The provided dataset was calculated via a practical experiment of orthogonal metal cutting. Tool-chip contact length is defined as the length in which the continuous produces chip remains in contact with the tool rake face during chip formation. In fact, this length is measured from the tool's tip to the point that the chip leaves the rake face. Different rational arrangements of cutting speed, feed-rate, and depth of cut have been chosen in this work to capture their associated tool-chip contact length. The dataset covers 44 different arrangements of cutting parameters. An optical microscope combined with image processing software is used to measure the tool-chip contact length.
