Computer numerical control (CNC) is the automation of machine tools by means of computers executing per-programmed sequences of machine control commands. This is in contrast to machines that are manually controlled by hand wheels or levers, or mechanically automated by cams alone.
Modern Machine Tools:
CNC machines: Introduction, principles of operation,
Types – Vertical machining centres and horizontal machining centres,
major elements, functions, applications,
controllers,
open loop and closed loop systems
Types of automatic machines,
Transfer machines
Introducing the innovative new temperature controller, MAXVU from West Control Solutions.
The MAXVU controller offers fast, reliable temperature control for packaging, textile and food and beverage machine builders on a budget.
MAXVU provides an uniquely large display, clearly visible from a distance and with a wide viewing angle.
The temperature controller has an extremely simple, easy-to-use set up menu, which concentrates on the essential parameters, meaning the controller can be set up in under 60 seconds for most common applications.

FMEA is a methodical, proactive strategy for assessing a process to determine where and how it might fail as well as to gauge the relative impact of various failures in order to pinpoint the areas of the process that require the greatest improvement. Teams utilise FMEA to assess processes for potential failures and to prevent them by making proactive process corrections as opposed to responding to unfavourable occurrences after failures have happened. With a focus on prevention, there may be a lower chance of injury to patients and staff. FMEA is particularly helpful in assessing the impact of a proposed change to an existing process and in evaluating a new process prior to implementation.

DETERMINATION OF MECHANICAL PROPERTIES OF E-GLASS EPOXY COMPOSITE”tulasiva
The project describes the mechanical fatigue behaviors by investigating in PMC,
in which twill type woven E-glass fibers as the fibrous reinforcement phase and
the Epoxy (Araldite) resin as the matrix phase. To enhance the mechanical and
physical characteristics of the Polymer Matrix Composite there is an addition of
Silicon Carbide (SiC3) and Calcium Carbonate (CaCo3). Once the composite are
layered by Hand Lay-Up process and cured, the specimens are specifically
geometricized for the individual Mechanical test like finding its behavior in
Tensile Test D-638 (ASTM), Flexure Test D-790 (ASTM). The specimens are
further inspected at nano-level textures to find its behavior, inspect the presence of
micro voids and relative adhesiveness between all the constituents.

The FMEA relates to a very broad spectrum on how effective this tool can be utilized as solver aid in dealing with the histories/pattern of failure in the product.
And how well can it be hierarchically deal with analysis the root cause of the problem.
This methodology is widely adopted in almost all manufacturing branch industries, due to its efficiency is tracking down all the possibilities occurrence in failure with the severity, occurrence, etc and other parameters to define the intensity of the failure being occurred.
To understand the tools usage a bit further, I have enumerated a case study via a example in this slides.
In view of Fatigue & Fracture Mechanics, the slides give a insight off the effects of the Creep and Fatigue Crack growth.
As both the fatigue and creep phenomenon is dynamic in nature due to the involvement of parameter w.r.t time.
Thereby the J contour Integral parameter is replaced by C-Integral by adopting Hoff's Analogy and Power's Law.
Titled as 'Automotive Tribology ", the concept of this poster presentation was to enlighten my fellow college persons to know the diagnosis/abbreviations behind lubricants used at automotive.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. INTRODUCTION
CNC CONTROLLER :
Devices that control machines and processes.
They provide capabilities ranging from simple point-to-point
linear control to highly complex algorithms with multiple axes of
control.
CNC Controller is the package of electronics and software that
take input either from g-code or the CNC control panel and
converts it to signals the CNC machine’s motors need to move the
CNC axes.
3. Why are they important?
• Improve the steady-state accuracy by
decreasing the steady state error.
• Help in reducing the unwanted offsets
produced by the system
• Control the maximum overshoot of the system
• Help in reducing the noise signals produced by
the system
• Help to speed up the slow response of an
overdamped system
4. TYPES OF CONTROLLERS IN CNC SYSTEMS :
1. Motion type CNC
Contouring systems
Point to point systems
2. Control loop CNC
Closed loop system
Open loop system
3. Number of axis type CNC
2-axis machines
2.5 axis machines
3 axis machines
4 axis machines
5 axis machines
5. Control Operating Modes For CNC:
CNC Machine Jog Mode
• most used CNC mode
• used to travel the CNC machine carriage ( or CNC
machine Slide) such as CNC machine’s axis
movement
CNC Machine MDI Mode or MDA Mode
• MDI (Manual Data Input) OR MDA (Manual Data
Automatic)
• semi automatic mode
• used to index tools, or to execute one block of
CNC code
6. CNC Machine Single Block Mode:
• CNC program consists of CNC program blocks
• CNC machine single block mode will not affect the machine spindle
rotation but it will only hold the tool feed after the CNC program block is
executed.
CNC Machine Auto Mode or Automatic Mode:
• Rarely seen a production shop CNC machine.
• In CNC machine auto mode when you press the cycle start button on
the machine control panel the whole CNC program will be executed.
• To run the CNC machine in auto mode there are some conditions must be
met.
