“…The available literature includes many publications on determining machining forces, determining and modeling the state of the cutting process of high-alloy steels in terms of selecting process conditions, determining its state or analyzing load, tool wear [8,13,14,25] or tool damage [5]. Machining of alloy steels, due to its alloy components that are difficult to cut, is generally problematic and requires the use of wear-resistant tools; attempts are also made to carry out machining in conditions different from standard ones, for example dry or using MQL [7,12,17,18,20,23].…”

The article presents the results of works on the analysis of using cutting forces and torque to determine AISI 304 stainless steel milling process state. The research and analyzes were carried out for the determine tool state and the process state itself. The tests were performed using Sandvik milling head, equipped with 345R-1305M-PM 4230 inserts . This study presents and discusses the obtained results determining the resultant value of the minimum and maximum cutting forces and the tool life. The results of observations of the tool's condition were presented.

“…However, the previous studies on coercive force measurements mainly focus on the micromechanism of the coercive force change. So far, only a few studies have investigated the influence of one-way stress on the coercive force of materials, and the impacts of complex stresses on the measurement results have not been considered, preventing successfully applying the research to engineering practices [15,16]. It is an effective way to ensure the safety of pipelines to adopt various advanced and targeted inspections to identify pipeline defects, judge the types of defects, and then carry out safety evaluation and maintenance [16].…”

To solve the above problems, this study conducted experiments on the relationship between coercivity and stress of X80 steel under different stress combinations.…”

Buried pipelines are prone to deformation under surface displacement, pressure occupation, and/or other actions, resulting in stress concentration. Conducting regular stress detection is an important approach to reducing pipeline accidents. This study performed experiments on measuring the coercivity stress of X80 steel, the most commonly used material for high-pressure large-diameter gas transmission pipelines. The coercivity of the specimen under different stress combinations was measured using the DC-driven coercive force measurement system, and the variation of coercive force with biaxial stress was also analyzed. The modified coercive force-stress expression of the generalized Hooke’s law was proposed; the model for the coercive force-stress relationship of X80 steel under the biaxial stress state was established based on this expression. The study indicates that the coercive force method is reliable for accurately measuring the stress of pipeline steel and evaluating the safety margin of in-service pipelines.
