Water jet cutting
Water jet cutting is a machining method that uses a high-pressure stream of water, sometimes with an abrasive material added, to cut materials. It is a non-thermal process so there is no heat affected zone on the material. Water jet cutting can cut a variety of materials either with just water or by mixing in an abrasive material for harder substrates. It has advantages over other cutting methods in that it produces no heat, fumes or burrs and can cut many material types, but has limitations in cutting speed for some harder materials.
Water jet machining WJM & AWJM
Water jet machining uses a high pressure stream of water, sometimes with an abrasive additive, to cut materials. Key aspects of the process include a water jet that travels at speeds of 540-1400 m/s to erode material from the workpiece surface. Parameters like pressure, abrasive grain size, and speed affect the performance and quality of cuts. Water jet machining provides advantages like flexibility, environmental friendliness, and stress-free cuts of many materials without heat or debris. However, initial costs can be high and material removal rates are low.
Water jet cutting technology
Water jet cutting is a versatile and precise cutting process that uses a high-pressure stream of water, with or without an abrasive material, to cut materials. It can cut almost any material and produces no heat-affected zone. There are two main types - pure water jets which are used for softer materials, and abrasive water jets which use abrasives mixed with water to cut harder materials. The process involves forcing water or a water-abrasive mixture through a nozzle at extremely high pressure to cut materials. It has many advantages over other cutting methods like lasers or EDM such as being safer, faster, and producing less heat and burrs.

Ultrasonic Machining by Ms Shikha Kashyap
Ultrasonic machining uses high-frequency vibrations to remove material by abrasion. It can machine hard and brittle materials to complex shapes with good accuracy. The process involves an abrasive slurry and a tool that oscillates at ultrasonic frequencies (over 18 kHz) to remove material. It is a non-traditional machining method that is not limited by the electrical or chemical properties of the work material. Recent developments include combining ultrasonic abrasion with electrochemical reactions to increase material removal rates.
Ultrasonic machining
This presentation gives an information about introduction to Ultrasonic machining covering the syllabus of Non Traditional Machining.
Ultrasonic machining
Ultrasonic machining uses a vibrating tool oscillating at ultrasonic frequencies to remove material from a workpiece with an abrasive slurry between them. Very little heat is produced since the tool never contacts the workpiece. This makes it suitable for hard, brittle materials like ceramics. The presentation discusses the process elements of work material, tool cone and tip, and abrasive slurry. It explains that hard, brittle materials can be machined and abrasives like boron carbide are commonly used. The tool design considerations are to resist fatigue failure while providing the proper stroke and mass.
Ultrasonic Machining
1. Ultrasonic machining is a non-traditional machining process that uses a vibrating tool to remove material from a workpiece submerged in an abrasive slurry.
2. The tool vibrates at high frequency (typically 20-40 kHz) and is gradually fed into the workpiece. The abrasive grains in the slurry are driven across a small gap by the vibrating tool and impact the workpiece, removing small particles.
3. Ultrasonic machining can machine both conductive and non-conductive materials like ceramics and is well-suited for hard, brittle materials. Key factors that influence the material removal rate include vibration frequency and amplitude,
Abrasive water jet machining
Abrasive water jet machining uses a high-pressure water stream to accelerate abrasive particles to cut through materials. It works by mixing abrasive particles into the water jet as it exits the nozzle. The coherent abrasive water jet can then cut hard materials through two mechanisms - erosion at shallow impact angles and deformation wear at deeper angles into the cut. Key process parameters that influence the cut include water pressure, abrasive flow rate, particle size, traverse speed, and stand-off distance from the workpiece. Abrasive water jet machining combines the capabilities of waterjet machining and abrasive jet machining to cut a wide range of materials with a narrow kerf even at great depths.
Water jet machining
Water jet machining uses a high-pressure stream of water to cut materials. It is a cold cutting process that produces no heat-affected zones. The water jet travels at supersonic speeds and erodes material when the local pressure exceeds the material's strength. Key components include a hydraulic pump to pressurize water, an intensifier to further pressurize it, and a nozzle to direct the jet. It can cut a variety of materials and offers advantages over other cutting methods like reduced burrs, flexibility of cutting complex shapes, and not producing heat or fumes. However, it is not suitable for high-volume production.

Unconventional manufacturing processes remove material using mechanical, thermal, electrical or chemical energy rather than sharp cutting tools. They are used for very hard, brittle materials that cannot be easily machined through traditional processes. There are several types of unconventional processes including abrasive jet machining (AJM), electrochemical machining (ECM), and laser beam machining (LBM). AJM works by using a high velocity stream of abrasive particles to remove material through micro-cutting or brittle fracture. Water jet machining (WJM) uses high pressure water to cut softer materials while abrasive water jet machining (AWJM) adds abrasive particles to the water jet to cut harder materials.

Ajm and wjm
Abrasive jet machining uses abrasive particles suspended in a gas or liquid to machine materials through erosion. Key points include:
- Abrasive particles like aluminum oxide or silicon carbide are accelerated to high velocities and directed at a workpiece to erode away material.
- Process parameters like abrasive size and flow rate influence the material removal rate, with larger abrasives providing higher removal.
- Applications include cutting, cleaning, etching, and polishing of brittle materials like ceramics, concrete, and composites that are difficult to machine with traditional methods.
- While allowing machining of hard materials, abrasive jet machining has low material removal rates and issues with stray cutting
Ajmandwjm
Abrasive jet machining uses abrasive particles suspended in a gas or liquid to machine materials. It can cut harder materials like ceramics and composites faster than conventional machining. The abrasive particles impact the workpiece at high velocities of 150-300 m/s, removing material through brittle fracture. Larger abrasive grain sizes and higher flow rates increase the material removal rate. Common abrasives include aluminum oxide, silicon carbide, and magnesium carbonate.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
