Effects of Solid Lubricants on hard turning

open access: yesProceedings of the 2nd International Conference on Electronic and Mechanical Engineering and Information Technology (2012), 2012
Product quality is one of the most important criteria for the assessment of hard turning process. However, in view of the high temperatures developed in hard turning process, the surface quality deteriorates due to the tool wear. Because of the strict environmental restrictions on the use of cutting fluids, new cutting techniques are required to be ...

HalluHard: A Hard Multi-Turn Hallucination Benchmark

open access: yesCoRR
Large language models (LLMs) still produce plausible-sounding but ungrounded factual claims, a problem that worsens in multi-turn dialogue as context grows and early errors cascade. We introduce $\textbf{HalluHard}$, a challenging multi-turn hallucination benchmark with 950 seed questions spanning four high-stakes domains: legal cases, research ...
