Introduction to mechanical engineering design & manufacturing withAkshit Rajput
The document provides an introduction to mechanical engineering design and manufacturing using Fusion 360. It discusses key aspects of mechanical engineering design including the design process, digital manufacturing, CAD/CAM/CAE software such as Fusion 360, and CNC machining. Some key points covered include the steps in the engineering design process, advantages of digital manufacturing, differences between CAD, CAM, and CAE tools, and differences between numeric control and computer numeric control systems.
Rapid prototyping and tooling techniques allow for the quick fabrication of prototypes and tools with minimal lead time based on CAD models. Stereolithography is one of the earliest techniques and works by curing liquid photopolymer resin layer-by-layer with a laser. Multijet modeling is similar but uses inkjet print heads to deposit photopolymer layers. Selective laser sintering works by using a laser to sinter powder materials layer-by-layer. Fused deposition modeling extrudes thermoplastic filaments layer-by-layer. Together these additive techniques provide fast and flexible options for prototyping and manufacturing.

The textile industry in Ethiopia produces cotton textiles like yarn, fabrics, bed sheets, and blankets. There are 35 textile enterprises in Ethiopia, both public and private. The largest textile factories are located in Addis Ababa, Amhara, and Southern regions. Kombolcha Textile Share Company has a spinning capacity of 7,000 tons of cotton per year and a weaving capacity of 22 million square meters of fabric annually. Issues facing the industry include over-reliance on cotton and poor production and material handling systems. Infrastructure challenges also limit private enterprises from operating in regional towns.
This document presents a seminar on the spinning layout of the Bahir Dar University Textile and Fashion Technology Institute.

This document discusses the use of electronics in knitting machines. It provides advantages of electronic control over mechanical control, such as higher speeds, easier programming, and greater versatility. It describes various applications of electronics like stop motions, yarn feeding systems, needle selection, and pattern selection. Microprocessors and computers allow storing large amounts of knitting data and programs. Computerized knitting machines can be programmed to move the carriage and select needles electronically for complex patterns. Overall, electronics have significantly improved knitting machine capabilities and productivity.
This document provides information about knitting machines used for fully fashioned garments. It discusses three types of knit garments: cut and sew, fully fashioned, and complete knits. Fully fashioned garments are knitted as individual shaped pieces that are then joined together. The document describes different types of fully fashioned knitting machines, including straight bar frame machines, flatbed machines, and circular machines. It provides details on the mechanisms and processes of loop transference and knitting actions on these machines. The goal of fully fashioned knitting machines is to produce custom pre-shaped garment pieces that are then assembled without cutting or excess fabric.
Warp knitting machines use specialized needles to interlock loops of yarn together to form fabric without weaving. The document provides cross-sectional diagrams of two types of warp knitting machines: a bearded needle tricot machine and a latch needle raschel machine, which use different needle configurations to form knitted fabrics in a single production step.
This document discusses quality control in the knitting process. It describes how effective quality control is important to reduce costs from defects, prevent customer dissatisfaction, and maintain quality. Several factors that can affect knitted fabric quality are discussed, including yarn properties, knitting machine parameters, process monitoring systems, and common fabric defects. Quality is maintained through controls on properties like loop length, tension, and defect detection.
This document discusses positive yarn feeding systems and how they affect fabric quality. It provides information on different types of positive yarn feeding systems including tape feed mechanisms and storage feeders. Positive yarn feeding helps control fabric properties and quality by providing uniform yarn tension and detecting faults before knitting. Modern systems use microprocessors and pre-calculated yarn requirements to precisely control yarn delivery. While positive feeding improves quality, it can also cause yarn breakage issues which manufacturers work to overcome through innovations like ceramic coated feed wheels.
Knitting is a fabric production process accounting for over 30% of total textile production. There are two main knitting techniques: weft knitting forms loops within each row from a single thread, while warp knitting produces fabric from vertically-running parallel warp yarns. A knitting machine consists of a frame to hold mechanisms, a yarn feeding system, a knitting area with needles and pattern control, a fabric take-down system, quality control devices, and a machine control and drive system.
This document discusses various aspects of knitting science, including how loop length controls fabric dimensions and properties. It establishes three basic laws governing knitted structure: that loop length is fundamental, loop shape determines dimensions, and the relationship between shape and length can be expressed in equations. Other topics covered include how warp let-off, fabric relaxation and shrinkage, knitted fabric geometry, tightness factor, and robbing back can all influence knitted fabrics. The document also discusses needle bounce, positive needle control, and the Cadratex unit for controlling fabric tube shape.
Knitting is a method of fabric formation using two or more needles to loop yarn into a series of interconnected loops. The basic elements of knitting include the yarn, needles, and stitches. Knitting can be done by hand or machine and produces fabrics that are elastic, breathable, and versatile for many applications.
This time, we're diving into the murky waters of the Fuxnet malware, a brainchild of the illustrious Blackjack hacking group.
Let's set the scene: Moscow, a city unsuspectingly going about its business, unaware that it's about to be the star of Blackjack's latest production. The method? Oh, nothing too fancy, just the classic "let's potentially disable sensor-gateways" move.
In a move of unparalleled transparency, Blackjack decides to broadcast their cyber conquests on ruexfil.com. Because nothing screams "covert operation" like a public display of your hacking prowess, complete with screenshots for the visually inclined.
Ah, but here's where the plot thickens: the initial claim of 2,659 sensor-gateways laid to waste? A slight exaggeration, it seems. The actual tally? A little over 500. It's akin to declaring world domination and then barely managing to annex your backyard.
For Blackjack, ever the dramatists, hint at a sequel, suggesting the JSON files were merely a teaser of the chaos yet to come. Because what's a cyberattack without a hint of sequel bait, teasing audiences with the promise of more digital destruction?

Elasticity vs. State? Exploring Kafka Streams Cassandra State StoreScyllaDB
kafka-streams-cassandra-state-store' is a drop-in Kafka Streams State Store implementation that persists data to Apache Cassandra.
By moving the state to an external datastore the stateful streams app (from a deployment point of view) effectively becomes stateless. This greatly improves elasticity and allows for fluent CI/CD (rolling upgrades, security patching, pod eviction, ...).
It also can also help to reduce failure recovery and rebalancing downtimes, with demos showing sporty 100ms rebalancing downtimes for your stateful Kafka Streams application, no matter the size of the application’s state.
As a bonus accessing Cassandra State Stores via 'Interactive Queries' (e.g. exposing via REST API) is simple and efficient since there's no need for an RPC layer proxying and fanning out requests to all instances of your streams application.

2. SDS-ONE system (Shima Seiki)
The most useful programs
include Knit-paint and Knit-
design.
3.
4.
5. Shima Seiki’s SDS-ONE system are as follows:
i) The Colour Number List
ii) Optional Line Function List
iii) Pattern Development Assignment
iv) Reference data for colours used for
WholeGarment® (WG) package
6. • overview and explanation of how these
concepts work together to allow for complex
designs to be programmed and knitted.
Specifically the Section provides an outline of
(1) basic programming procedure, (2)
package programming and (3) WG package
programming.
7. Digital knit programming involves a series of
procedural steps to translate the envisaged
design into a computer language or code using
the CAD/CAM (Computer Aided Design /
Manufacture) system.
The data is then saved onto a disc (or the
network) and is transferred to the knitting
machine.
8. For Shima Seiki, the CAD system developed is
known as SDS-ONE. The SDS-ONE system is
a totally integrated knit production system that
allows all phases including planning, design,
evaluation and production
9. Outline of basic programming
procedure
In order to knit a design using a Shima Seiki
industrial knitting machine, it must be
programmed. The steps involved are:
(1) Design preparation, (2) Programming the
design, (3) Design Processing, and (4) Knitting.
10. 1. Design preparation
Design preparation involves the initial planning
and development of the design ideas. This
includes inputting the design into the CAD
system. The knitting CAD system is specific to
the industrial knitting machine. For Shima
Seiki knitting machines the CAD system is SDS-
ONE.
11. The Knit-
paint
program is
where all
technical knit
programs are
constructed,
processed
and
checked,
through the
knit
simulation
function
12. • In contrast the Knit-design program is for design work.
Knit-design allows for the design of 2D surface stitch
architectures, yarn and colour selection to be virtually
knitted (simulated), as well as colourways tested. The
design program has a broad file format, allowing for
jpeg, tiff, and bmp files to be imported into the
system. Therefore artwork, for example for a jacquard,
can be scanned into the system, cleaned (through
colour reduction) and prepared.
13. SDS-ONE knit-design program working page
with knit simulation
Within the
Knit-design
program there
is a library of
stitch
architectures,
which can be
accessed
to create
complex
fabric
structures
14. 2. Programming the design
The design is converted to programming language
and data is inputted and consists of 3 parts;
(1) the structure pattern, (2) the option lines and
(3) the pattern development assignment
(2) The programming is undertaken through Knit-
paint.
15.
16. • Specifically, the structure pattern or design
area (Figure 3.36, 1) is set, based on the stitch
code colour number list (refer to Stitch Code
Summary). Every stitch type or movement of
a stitch is represented by a colour/number.
17. The option lines inform the knitting machine how
the design is to be knitted. Each option line
represents a different part of the knitting
process, such as the selection of yarn carriers,
and which sections of the design are to be
repeated. The option lines ultimately provide the
knit program with some flexibility, as the inputted
data in the option lines can be changed at the
processing and at the knitting stage.
18. The pattern development assignment also
provides support information, similar to the
option lines, about the width and placement
of the knitting on the machine.
19. 3. Design Processing
The design is processed and saved to a formatted disc or
network to ensure the knit program can be read by the
knitting machine. In processing, the knit parameters
are set and the machine type to be used is specified.
The knit parameters are based on the option lines and
can include for example economisers (repeat sizes),
digital stitch and takedown values and the selection
of yarn carriers.
21. 4. Knitting
The knitting machine is set up. Yarn is selected
and threaded through the tension devices to
the yarn carrier. Then the knit program is
selected, read, and knit parameters set and/or
adjustments made via the machine display
panel. The knit program is then knitted.
22. Package programming
Package is an extension of basic programming. Through
the use of Package software, the programming of a
design is simplified. Package software uses a system of
registered colours, with each colour (and number)
representing a different knit package or combination
of stitches. Package allows for complex design
outcomes, particularly 3D seamless knitting, to be
more readily visualised and communicated in a
simplified 2D format.
23. WholeGarment® package programming
seamless knitting technology creates a complete
garment with minimal or no cutting and
sewing required, thus eliminating seams.
Seamless knitting is made possible by machine
technology that allows tubular rib transfer.
25. • When Package Software is applied to Shima
Seiki’s WholeGarment® technology, three
stages for programming need to be
completed before the design can be knitted.
This is similar to standard package
programming and includes (1) the Package
base pattern, (2) the Compress pattern and
(3) the Development pattern (Figure 3.44).
26.
27. 1. Package base patterns
Package base patterns are based on the package
library developed by Shima Seiki. In addition,
for more complex designs, the required
package base patterns may need to be self
constructed by the knit programmer.
28. 2. Compressed pattern
The garment design is translated into programming
language. The compressed pattern consists of three
parts; (i) the base pattern, (ii) the front design area
and (iii) back design area. The base pattern provides
the information on the overall garment shape or
structure. This information includes variations with
front and back, such as necklines or variations required
for a cardigan type garment.
29. 3. Developed pattern
The Compress Pattern is expanded to become the
‘Developed Pattern’. The process of expanding the
pattern combines the three parts of the Compressed
Pattern and develops each package. This process is
semi automatic and is achieved by using the processing
procedure of Package development. Developing the
packages converts the program to the standard Shima
Seiki colour code language, where one colour per
square equals one stitch type.
30. Once expanded, the Developed Pattern can be
processed. Processing is a semi automatic
procedure carried out through the Knit-paint
software and involves inputting specific
information such as the yarn carriers,
economisers and takedown into the program and
converting the program to a .000 file, so that the
program can be read by the knitting machine.
