Laser specific energy consumption: How do laser systems compare to other manufacturing processes?
نویسندگان
چکیده
Laser material interactions are routinely praised for their selective processing and high rates. However, this does not guarantee that the total manufacturing system has a low energy intensity compared to conventional processes. This paper presents results of collaborative UK China research project improve comprehension consumption carbon emissions laser-based manufacturing. A range individual laser cutting, welding, cleaning processes were studied assess efficiency, including its ancillary subsystems (e.g., cooling extraction). The developed systematic analysis method, adapted from BS ISO 14955-1:2017, which incorporated time subsystem level studies quantify all components system. Previous identified system's most significant contributor auxiliary or supporting subsystems, emission. using only absorbed radiation evaluate efficiency is misleading. All evaluated followed negative correlation between rate (kg/h) specific (J/kg). new data conclude have relatively alternatives. can be used identify where improvements systems made. comprehensive comparison allows manufacturers select environmental impact.

Improving Laser Manufacturing Processes by Means of Multiphysics Simulations
In this paper we present an example of how laser manufacturing technology can benefit from the use of realistic process simulations. The general design of the multiphysical model used allows for the simulation of different kinds of laser processes such as welding, cutting or more recently even ultra-short pulse ablation [1]. The model is able to perform the simulation of the complete process, t...

Gluttony and sex in female ixodid ticks: how do they compare to other blood-sucking arthropods?
The central issue dealt with here is the role of copulation in the control of feeding behaviour in ticks and some haematophagous insects. Female ticks of the family Ixodidae normally engorge to approximately 100 x their unfed body weight, and then drop from the host, produce and lay eggs, and die. Virgins, on the other hand, normally do not exceed 5-40% (depending on species) of the normal engo...
متن کاملHow do clinical trial participants compare to other patients with schizophrenia?
OBJECTIVE Patients with schizophrenia enrolled in a trial of long-acting injectable risperidone at multiple sites of the Veterans Health Administration (VHA). We considered if the trial participants were representative of the targeted group of high-utilization patients with poor adherence to anti-psychotics. METHODS Participants' characteristics, health services utilization, and cost in the y...
