Monitoring of Chip Flow State in Drilling With Tool Wear Progress
Authors: Matsumura Takashi , Tamura Shoichi 
Published: August 2024

Abstract
The chip flow control is a critical issue in the automated cutting operations because the chips scratch to deteriorate the finished surfaces. The chip clogging also induces tool breakage as well as human intervention in the automated production. The chip flow state, therefore, should be monitored to prevent from such the cutting troubles with forecasting the chip clogging. It is well known that chip flow state changes with the tool edge shape, which may be associated with the tool wear progress. The chip flow monitoring would also be effective in estimation of the tool wear size. This study discusses irregularity of cutting force associated with the chip flow change in the tool wear progress. The force signals were acquired in the direct (DC) and the alternating currents (AC). The AC signals of the horizontal components in the cutting force is sensitive to the chip flow change. The resultant of the horizontal components characterizes the irregularity of the chip flow state. The chip flow direction is also analyzed in a cutting force model, in which the chip flow angle is determined at the minimum cutting energy. In the model, the change in the chip flow angles is simulated with the tool feed in the hole. The chip flow direction changes toward the radial direction when the chisel and the thinning parts exit from the workpiece. When the tool wear becomes large, the chips flow toward the radial direction more and the chip clogging occurs in the flute.

Abstract
This paper is concerned with an advanced control system of a sand molding robot in a casting industry. Sand molding machines have been mainly used in the foundries with mass production line. However, it is difficult to apply the conventional sand molding machines to foundries with cell production system which are required a high-mix low-volume production. Therefore, the sand molding robot system using a vertical articulated robot automating the sand molding process with the cell production system has been progressed more recently. In this robot system, the force control approach has been applied to the sand compaction process. However, the sand mold compacted by the robot was low strength and variation in the strength.
Therefore, we develop the sand compaction control system in the sand molding robot. The sand in the metal frame is molded by the robot equipped with thrusting and stamping tools. In this system, we propose the admittance control for compacting the sand with desired robot motion and force. The efficacy of the developed sand compaction control approach was verified by the experiments with the sand molding robot.

Abstract
The quantification of repetitive movements, known as repetitive action counting, is critical in various applications, such as fitness tracking, rehabilitation, and manufacturing operation monitoring. Traditional methods predominantly relied on the estimation of red-green-and-blue (RGB) frames and body pose landmarks to identify the number of action repetitions. However, these methods suffer from several issues, such as instability under varying camera viewpoints, propensity for over-counting or under-counting, challenges in differentiating sub-actions, and inaccuracies in recognizing salient action poses, etc. Our method integrates joint angles with body pose landmarks to address these issues, thereby surpassing the performance benchmarks of existing state-of-the-art repetitive action counting methodologies. The efficacy of our approach is underscored by a Mean Absolute Error (MAE) of 0.211 and an Off-By-One Accuracy (OBOA) of 0.599 on a public repetitive action counting data set, Rep-Count [1]. Comprehensive experimental results demonstrate the effectiveness and robustness of our method.

Published: August 2024

Abstract
This paper deals with the improvement of wire-sawing performance in vacuum by applying vibration to the saw wire. The performance of wire-sawing in vacuum has been investigated for future lunar and planetary explorations. Nickel fixing abrasives adhered on a rock specimen in vacuum and the abrasives slipped on it so that the rock was hardly cut. The vibration of a tool generally accelerates the removal rate. The flexural roller guide in the wire-sawing machine vibrated the saw wire, and the vibration improved the performance.

Published: August 2024

Abstract
Digital metal forming is being developed to reduce production time and increase product precision in low volume metal forming. This paper discusses the development of a novel digital metal forming system that incrementally works metal parts without specialty dies and tools. An electric ram is utilized to provide the bending force, and the die and workpiece position is controlled by a linear axis. A multi axis force sensor and a machine vision camera are equipped to monitor forces acting on the ram and the part bend angle, respectively, during the process. A C++ program is created to integrate the interpolation, motion control, and force and camera measurement tasks. The function of the system is demonstrated with a sheet metal bending experiment in which an aluminum bar is bent to 30° using an iterative learning controller. An analytical bending model estimating the springback angle after bending is utilized and the controller gain is obtained and adjusted based on the linearized gain of an analytical bending model. The results demonstrate the controller is able to bend the bar to the desired angle in under three iterations in spite of model uncertainties. The designed digital metal forming system is expected to coordinate monitoring system tasks, motion control tasks, and the iterative learning controller to obtain a part with a desired shape in a completely automated process for more types of free forming processes, such as incremental sheet forming.

Published: August 2024

Abstract
Cooperative robotic additive manufacturing (C-RAM) offers the fabrication of large-scale components through the integration of multiple out-of-bounds robotic systems. However, factors such as wear and tear, calibration drift, temperature fluctuations, and vibrations impact the precision of the robots, leading to anomalies including dimensional inaccuracies, layer morphology issues, or mechanical defects. These anomalies adversely affect the strength and fatigue life of components. Ensuring CRAM systems are robust to defects is critical to the reliability and scalability of large-scale systems. We introduce a novel C-RAM system equipped with multi-fidelity multi-scale sensing (i.e., in-situ thermal imaging and laser scanning) to characterize process quality of a robotic fused deposition modeling (FDM) process. Control and data acquisition are designed through a ROS2-based digital twin modified for FDM fabrication control, allowing robust control of process parameters such as feed rate and extrusion multiplier. The system is evaluated via a case study on the effect of extruder temperature on material deposition height. Sensing data is analyzed, displaying high and low-fidelity quality indicators across extruder temperatures.

Published: August 2024

Short-term mega sporting events provide an opportunity for students to not only gain a memorable career experience but also enhance student skills and learning. However, very few (if any) researchers have explored students’ confidence related to key skills before and after such an event. Thus, the purpose of this study was to assess the effect of experiential learning at the National Football League’s 2023 Super Bowl LVII mega event on students’ learning outcomes. Students (N = 103) responded to an online survey distributed to assess their self-confidence across 18 learning-outcome skills covering problem solving, communication, sport-industry knowledge, and professional development. Each dependent-sample t test done to examine the students’ self-confidence with the individual learning outcome skills was significant (p < .001) and had meaningfully increased (Cohen’s d range: 0.47–0.97) from pre- to postevent. The results suggest that students can experience a notable increase in self-confidence when volunteering at a short-term mega sporting event. From a practical standpoint, the results provide sport management educators with strong evidence of the meaningful student learning related to problem solving, communication, sport-industry knowledge, and professional development that can occur with a single short-term mega-event experience.

ObjectivesSpecialty nurses play a significant role in improving patient care; however, little is known about the factors affecting their work engagement. This study aimed to explore the relationship between role stress and work engagement among specialty nurses in China.DesignA descriptive, cross-sectional study was applied in this study.SettingThe study was conducted in the Henan Provincial People’s Hospital in China.ParticipantsFrom March to April 2023, we conducted a cross-sectional descriptive study, using convenience sampling to recruit 972 specialty nurses from 42 specialised fields in China.MethodsAn online questionnaire survey was conducted using the Basic Information Questionnaire, Role Stress Scale and Specialty Nurse Work Engagement Scale. The collected data were analysed by using SPSS 21.0 software. The differences in total work engagement scores between subgroups were investigated using a single-factor analysis of variance. A Spearman’s rank correlation and a Pearson’s correlation were used to determine the relationship between general information, role stress and work engagement. A ridge regression analysis explored the impact of role stress on work engagement.ResultsThe total score of role stress was (52.44±19.92) and the total score of work engagement was (140.27±17.76). Among the scores of various dimensions of specialty nurses’ work engagement, the standardised score for work attitude was the highest (4.54±0.56), followed by work values (4.46±0.64); the standardised score of work enthusiasm and focus was the lowest (4.22±0.64). Additionally, role ambiguity (r=−0.352, p<0.001), role conflict (r=−0.367, p<0.001), role overload (r=−0.313, p<0.001) and role stress (r=−0.380, p<0.001) were negatively correlated with work engagement. The total score of role stress was negatively correlated with the total score of work engagement; the results of ridge regression analysis showed that age, professional title and role stress explain 14.6% of the variance in work engagement.ConclusionOur study found that specialty nurses’ work engagement was mid-level or above. Role stress was significantly and negatively correlated with specialty nurses’ work engagement, which was an important predictor of their work engagement. Nursing managers should instate effective measures to reduce role stress, thereby increasing work engagement.

ObjectivesTo descriptively compare and contrast intervention techniques for preschool children with features of developmental language disorder (outcome: oral vocabulary) and speech sound disorder (outcome: speech comprehensibility) and analyse them in relation to effectiveness and theory.DesignThis is a systematic review with narrative synthesis. The process was supported by an expert steering group consisting of relevant professionals and people with lived experience.Data sourcesOvid Emcare, MEDLINE Complete, CINAHL, APA PsycINFO, ERIC, and Communication Source from January 2012 were searched. Relevant studies were obtained from an initial published review (up to January 2012).Eligibility criteriaInterventions for preschool children (80% aged 2:0–5:11 years) with idiopathic speech or language needs; outcomes relating to either oral vocabulary or speech comprehensibility.Data extraction and synthesisSearches were conducted on 27 January 2023. Two independent researchers screened at abstract and full-text levels. Data regarding intervention content (eg, techniques) and format/delivery (eg, dosage, location) were extracted. Data were synthesised narratively according to the methods of Campbellet al.Results24 studies were included: 18 for oral vocabulary and 6 for speech comprehensibility. There were 11 randomised controlled trials, 2 cohort studies and 11 case series. Similarities included a focus on input-related techniques and similar therapy activities. Speech studies were more likely to be professional-led and clinic-led, rather than at home and through a parent. Analysis was restricted by heterogeneity in study design and terminology, as well as gaps within intervention reporting. Information deemed important to the expert steering group was missing.ConclusionsSimilarities and differences between intervention techniques for oral vocabulary and speech comprehensibility have been identified and synthesised. However, analysis of effectiveness was limited due to issues with study design and heterogeneity within studies. This has implications for the progression of the evidence base within the field.PROSPERO registration numberCRD42022373931.

IntroductionPoor communication about serious injury in older adults can lead to treatment that is inconsistent with patient preferences, create conflict and strain healthcare resources. We developed a communication intervention called Best Case/Worst Case-intensive care unit (ICU) that uses daily scenario planning, that is, a narrative description of plausible futures, to support prognostication and facilitate dialogue among patients, their families and the trauma ICU team. This article describes a protocol for a multisite, randomised, stepped-wedge study to test the effectiveness of the intervention on the quality of communication (QOC) in the ICU.Methods and analysisWe will follow all patients aged 50 and older admitted to the trauma ICU for 3 or more days after a serious injury at eight high-volume level 1 trauma centres. We aim to survey one family or ‘like family’ member per eligible patient 5–7 days following their loved ones’ admission and clinicians providing care in the trauma ICU. Using a stepped-wedge design, we will use permuted block randomisation to assign the timing for each site to begin implementation of the intervention and routine use of the Best Case/Worst Case-ICU tool. We will use a linear mixed-effects model to test the effect of the tool on family-reported QOC (using the QOC scale) as compared with usual care. Secondary outcomes include the effect of the tool on reducing clinician moral distress (using the Measure of Moral Distress for Healthcare Professionals scale) and patients’ length of stay in the ICU.Ethics and disseminationInstitutional review board (IRB) approval was granted at the University of Wisconsin, and all study sites ceded review to the primary IRB. We plan to report results in peer-reviewed publications and national meetings.Trial registration numberNCT05780918.

Published: August 2024

IntroductionOropharyngeal dysphagia (OD) is difficulty manipulating a food bolus from the mouth to the throat. Up to 70% of older adults develop OD; however, it is unmanaged in primary care, leading to avoidable hospitalisation.ObjectiveThis behavioural science realist review aimed to develop programme theories to describe how interventions facilitate primary care healthcare professionals (HCPs) to proactively manage OD.MethodsWe developed initial programme theories (IPTs) inductively using the expertise of stakeholders and deductively using the theoretical domains framework (TDF). Databases were searched to identify evidence regarding contexts, behavioural mechanisms and outcomes related to proactive management of OD and comparative behaviours which offer transferrable learning. IPTs were tested with the evidence to confirm, refine or refute, to produce final programme theories.Results36 sources of evidence were included. Five final programme theories were generated explaining how primary care HCPs can be facilitated to proactively manage OD: (1) OD education and training, (2) checklists with OD signs and symptoms, (3) incorporating OD identification into existing workflow, (4) making HCPs aware that older adults and carers expect them to manage OD and (5) raising awareness of the adverse outcomes of OD.ConclusionThe five programme theories provide the behavioural mechanisms by which an intervention may facilitate primary care HCPs to proactively manage OD. Through the programme theories’ linkage to the TDF, behaviour change techniques (BCTs) mapped to the relevant TDF domain can be selected for an intervention. Operationalisation of selected BCTs into a coherent intervention package should be undertaken using codesign methodology.PROSPERO registration numberCRD42022320327.

Published: August 2024

ObjectiveThis study aimed to investigate the impact of nutritional support on the clinical efficacy in hospitalised tuberculosis patients with nutritional risk.MethodsWe selected a total of 266 eligible patients with tuberculosis for the experimental and 190 patients for control groups. The patients in intervention group received adjusted dietary structure, enteral nutrition via oral intake or gastric tube, total parenteral nutrition and combined enteral and parenteral nutrition. We recorded various factors, including age, sex, underlying disease, tuberculosis type, nutritional risk at admission, serum albumin (ALB), body mass index, complications during hospitalisation, nutritional support status, serum ALB before discharge and length of hospital stay.ResultsThe incidences of nutritional risk in the control and experimental groups were 64.41% and 64.72%, respectively, with no statistically significant differences in baseline characteristics. The occurrence rates of complications and secondary infections in the experimental group were 57.89% and 51.5%, respectively, which were significantly lower than the control group’s rates of 70.00% and 56.31%. These differences were statistically significant. The experimental group had a significantly shorter hospital stay (16.5±7.54 days) compared with the control group (19.55±7.33 days). Furthermore, the serum ALB levels of patients in the experimental group were higher on discharge than at admission.ConclusionHospitalised patients with tuberculosis often face a high incidence of nutritional risk. However, the implementation of standardised nutritional support treatment has shown promising results in improving the nutritional status of tuberculosis patients with nutritional risk. This approach not only helps reduce the occurrence of complications but also enhances short-term prognosis and improves overall clinical efficacy.
