Human Observational Data in a Production Environment

A heterogeneous dataset of human measurement data and human-generated text. This dataset was generated by TechSolve Inc. (techsolve.org) as a collaborative effort with NIST. Respondents were asked to observe and evaluate a machining process in which a rotary bit (the "tool") removed layers of a workpiece until the tool was worn to exhaustion. One trial and 19 official experiments were completed, one for each of 20 tools. Respondents were tasked with completing a survey in which they recorded their measurements of tool flank wear along all four tool chamfers, recorded their description of the cut in natural language, and rated the process and tool condition on a Likert scale, along with other measurements.
