Cutting condition is a pivotal factor affecting cutting performance in the turning process, especially in marine engineering, where materials must withstand the challenges of maritime environments. This study presents an experimental investigation of the impact of cutting process parameters on surface roughness, Vicker hardness, and cutting temperature in the turning of C45 steel, a critical material for marine applications.

Cutting force (CF) is one of the most important factors in improving machining efficiency. It directly affects the cutting tool life and the quality of the product. This paper presents the results of building a model to predict the value of the cutting force components using a back-propagation (BP) neural network when dry and hard turning SKD11 steel after heat treatment.

This paper presents the survey results of the relationship between the value of cutting force and the tool flank wear with the cutting parameters in dry turning SKD11 steel with a hardness above 54HRC. With the aim of surveying the change in cutting force and flank wear, each experiment was carried out with several successive cuts until the cutting tool was destroyed.

This paper presents fundamental problems and challenges. However, apart from these difficulties and challenges, Vietnam has many advantages in developing labour resource for exporting Vietnamese seafarers to the world labour market. Vietnam should take these advantages to overcome challenges and dilemmas, otherwise these problems would turn into long–term problems which are really hard to recover

In this research, the influence of the cutting parameters including cutting speed, feed rate and cutting depth on the flank wear and surface roughness was analyzed by using 2k experimental model with some center points. The results investigated that the feed rate is the most significant parameter effecting on the surface roughness in the machining process and the cutting speed strongly affects on the flank wear in the hard turning of sintered tungsten carbide using CBN inserts.

A hybrid process combining the turning-burnishing operation is a prominent solution to improve productivity due to the reduction in the auxiliary time. The objective presents a parameter-based optimization of the compressed air-assisted turning-burnishing (CATB) process to enhance the Vickers hardness (HN) and decrease the roughness (SR). The inputs are the cutting speed (V), depth of cut (a), feed rate (f), and ball diameter (D). A turning machine was used in conjunction with the turning-burnishing device to perform the experimental runs for aluminum 6061.

This paper focuses on the exploitation of the response surface methodology (RSM) to determine optimum cutting conditions leading to minimum surface roughness and cutting force components. The technique of RSM helps to create an efficient statistical model for studying the evolution of surface roughness and cutting forces according to cutting parameters: cutting speed, feed rate and depth of cut. For this purpose, turning tests of hardened steel alloy (AISI 4140) (56 HRC) were carried out using PVD – coated ceramic insert under different cutting conditions.

The present study reports on the application of accelerated cooling environment (ACE) in hard turning of AISI D2 steel (55 ± 1HRC) using mixed ceramic insert (Al2O3 + TiCN) which is rarely being investigated and to address the major problems of brittle fracture of tool tip that arises through cutting forces and friction at tool-work and chip-tool interface.

The results show that the tool wear was influenced principally by the cutting time and in the second level by the cutting tool hardness. On the other hand, cutting time was the dominant factor affecting workpiece surface roughness followed by cutting speed. Finally, the multiple response optimizations of tool wear and surface roughness were carried out using the desirability function approach (DFA).

The present study aimed to develop the predictive models of average tool-workpiece interface temperature in hard turning of AISI 1060 steels by coated carbide insert. The Response Surface Methodology (RSM) and Artificial Neural Network (ANN) were employed to predict the temperature in respect of cutting speed, feed rate and material hardness. The number and orientation of the experimental trials, conducted in both dry and high pressure coolant (HPC) nvironments, were planned using full factorial design. The temperature was measured by using the tool-work thermocouple.

In recent times, „Blended Instruction‟ - an effective method of instructions utilizing e-Learning materials in English education - consists of an individual learning part, a collaborative learning part and a teacher instruction part. In the individual learning, students act out model dialogues in the WBT courseware which incorporated a high quantity of video and sound clips. In the collaborative learning, students perform the dialogues in pairs and assessed each other‟s performance.

This paper presents results of a research on hard turning of 9XC and X12M alloy steels to explore the influence of workpiece’s hardness on machined surface roughness and topography at selected cutting conditions. It is evident that the surface roughness was directly proportional to the increase of the workpiece’s hardness from HRC = around 50 to higher than 60. Moreover, lower hardness resulted in worse surface roughness.

Many factors are thought to increase the chances of misrecognizing a word in ASR, including low frequency, nearby disfluencies, short duration, and being at the start of a turn. However, few of these factors have been formally examined. This paper analyzes a variety of lexical, prosodic, and disfluency factors to determine which are likely to increase ASR error rates. Findings include the following.

I tried to find the words. We all do it, I wanted to say. You do it, I wanted to say. I had to do it, I wanted to say. But what came out, when I opened my mouth, was nothing. Dad's hands tightened on my arms and for a moment, I was sure he was going to beat the hell out of me, really beat me, like you saw some of the others dads do on the estate. But then he let go of me and turned round and stormed out the flat. Mum stood in the door to my room, sagging hard against...

I stood as a man might stand who sees a vision, hardly breath- ing. I made no sound, yet she turned and saw me, sheltered as I was by the dappled trunk of a tall plane-tree. It was as if I had called, and she had answered. I knew she remembered me, and that she did not misunder- stand my presence. There was no anger in her face, only surprise, and a light which was hidden as she dropped her head, and passed on through the gate. I could have sung the song of the stars. She had not forgotten me since the afternoon. The look in my eyes...

THERE was a ripple of chimes through the frosty air as Catherine Murchison turned from King's Walk into Lombard Street, and saw the moon shining white and clear between the black parapets and chimney-stacks of the old houses. St. Antonia's steeple was giving the hour of three, and a babel of lesser tongues answered from the silence of the sleeping town. Hoar-frost glittered on the cypresses that stood in a garden bounding the road, and the roofs were like silver under the hard, moonlit sky.
