Transcript of Company
When a company needs to be better and more profitable in the global market, it has to follow strict rules such as...
Design plan and Manufacture
Lower unit cost
Reducing the design and development time
Creating concepts for final solutions
Mechanical Design software
Tools for 3D models
The tool box is a large tool that is based in solid works and is extremely powerful when used right. It is, in its basic form, a huge index of parts that are regularly used in an engineering project i.e. skews, bolts and nuts. This index is a quick and easy alternative to trawling through numerous pages in books looking for the correct part.
From the design section, engineering drawings can be used in the user manual creation. These can be directly linked to the model and updated whenever a part is changed or added. This can happen extremely fast.
Designers of manuals can make a basic template of where pictures will be place then after they can start on what they want the instructions to look like. While doing this they can collect the drawings without affecting the model, this can happen before the 3D product has been finished.
This helps as all the designers can be working together at the same time without having to wait for the Model to be created before doing the instructions. This saves a huge amount of time improving release dates and profits.
Analysis is used in software to investigate a completed product. These tests can come in many different forms from stress tests, heat tests and even injection moulding flow tests.
If these tests aren't carried out it could harbour serious problems which could cause products to be either held back or recalled after sale. With these tests products can be fixed much earlier which saves time. Can help fix problems before they even appear.
Products Life Cycle
This system is the traditional way of organizing how the operations of the business is done. In a simple definition the stages go one after the other. This is dubbed as the over the wall technique. A product will go through the stages but has to have been completely finished before it can move on.
This is how all to data businesses are run. It is a very organized system which allows companies to be constantly working around each other while not getting in each other’s way. It means that stages are allowed to overlap, meaning a shorter time period and easier communication between departments and stages.
3D software allows users to simulate the products or parts motions. this gives a great visual representation of the parts moving, working and reacting with each other. most software often has a collision detection system which which can very quickly warn a user when a product has two parts that will hit each other. this means a designer can easily and quickly find a problem and solve it within a few moments, ensuring that the end product has no problems and that it can be manufactured with the knowledge it will work correctly when put together. If this wasn't the case then parts would probably have to be re-called after creation due to underlying problems which would then increase the time it takes to release a products again reducing profits.
the life cycle of a product is something that always has to be investigated as it is the deciding point to how long a product will last with out breaking or deteriorating. it can show a numerous amount of options which can determine what the product need to work the best through its life. this system works due to the varying criteria that can effect the properties of a material.
things like strength, weight and even the environmental impact can be a factor when deciding on how the product needs to exist. new, cheap, lighter (but still strong) materials can be chosen. The products can be thinned to lessen the weight further without effecting strength and the environmental impact should be lessened dramatically.
Types of tests
When using the ‘Hole wizard’ tool on solid works, it allows a user to find all the information of bolts and skews . There are a few different types of holes to choose from. You have: Counter bore, countersink, Hole, Straight Tap, Tapered Tap and Legacy. Solid works gives the user all of the information on theses as they are all saved onto a database , plus if they want to change the type of hole or the size after it’s been set the measurements get automatically updated.
When trying to do all of this manually, the user has to look and research fully into what each hole is used for and if its not in a data base they will waste their time researching.
Simultaneous Engineering System
Sequential Engineering Systems. (Traditional)
The large problems are the fact that the time it takes to get through all of the stages.
And the fact that there is no simple way to deal with problems down the line. If something does arise the product has to go back through each stage till it is fixed. This causes even more time for the product to be finished.
Although it can have problems like it being hard to manage or working around material that is being used is several different stages. It has a vast amount of positives which improve the company’s time to market and profitability.
Not only does it have these effects but it also allows for quicker identifying of problems and can mean that they are resolved a lot quicker.
Design for Manufacture and assembly (DFM/DFA)
This is the point that ensures that a large variety of methods, tools and processes are used to manufacture and assemble products, doing this makes it easier and faster for products to be made.
Failure mode and effective analysis (FMEA)
This is a system that is put in place to make it faster to find and determine problems with parts/products. Analysis can come in tests forms, like stress tests that are done to fine the weakness or weakest parts of a part.
This is a process created as a preventative measure for failed parts due to mistakes. Usually done via machines having parts that only take in the correct shaped parts, this means that if the part is shaped so it can only fit in one way making it impossible to fit in any other way.
Statistical and Historical Methods.
Taguchi created methods for taking all the data from designs to make the variations in machining as small as possible. This means that everything is logged and it is very hard to have incorrect parts/products.
For the simultaneous engineering system to work efficiently and with speed teams of people are needed for specific tasks. This allows for maximum work load to to be taken on and completed in an immensely fast amount of time!
Design and Development
Quality and Maintenance
The manufacturing side of the company will be given as much of the products information as possible at the start of its creation. This allows for each area to understand the product and ensures that each team can work simultaneously decreasing it products whole Lead time.
Doing this also allows for a lot more planning to be done, meaning the right tools and data is gathered. This system makes certain that all the right preparation is done so work is never delayed.
The non-engineering based area of the company is the basis for the whole company's success. Without it it would be hard to even start a product, let alone finish it.
These areas shorten lead time and push up profits via dealing with customers, advertising and general purchasing. Plus, they as always looking for ways to capitalize i.e. investments in other companies or products.
Data is the key
Product Data Management
Reducing the Manufacturing time
Computer aided manufacturing (CAM)
a planned process to create a final product
Product data management can be simply described as a system a company uses to log all data from past to present in an ordered, easy to find and protected manor, aiding staff when they are working.
When a product is made it will always have a purpose, whether it is a wall bracket having to support weight, or a moulding device, everything designed needs to be able to work without breaking. Tests are done to understand the products tolerances and what could be changed to make the product better. Tests include Structural, Fluid, Thermal, Sustainability, Motion etc. In a workplace that doesn’t use 3D software they would have to be running tests on real models and would have to be calculating every answer. This is why almost all large engineering companies use software with the capability to understand a product and will be able to product detailed results with high speeds. This cuts down human error and means the company can increase its profits and decrease lead time on the creation of products.
This data is can vary immensely. usually a company will put all the data from every sector of the business. This means that any sector is able to look into related data to help them progress, eliminating human errors such as lost files or just general forgetfulness.
Engineering and Non-engineering based data
Database Management systems
These are the systems (mostly in a software form) that deal with the maintenance of the company's data
Linking of data
DBMS allows for easy availability when it come to data. it ensures that the right parts of the company get the data that will be most useful to them.
The checking process is done to ensure the manufacturing process has worked fine and to make certain that the product is up to the right standards for selling it to customers.
The process is done via quality control, undertaking tests and inspections.
The first stage of creating a product is to design it, which also means there are many processes that need to be done to ensure the product will be profitable while still up to standard.
The design team will do such things as: selection of materials, testing, drawings and approximate costs. These are the basic first steps to a manufacturing process.
Planning is a vital key point in the process, without it the whole company would crumble. this is where purchasing of materials and tools, assembly, drafting, manufacture methods and marketing are all done.
Along with this 3D modeling software allows for coding to take place. If a company uses CNC machines they are able to generate NC code that the machines can read and transcribe this data into motion.
The manufacturing process is where all of the companies hard work leads to. This process needs everyone before it to be working or itself wouldn't be able to operate.
Even with automated CNC machines workers still need to be given information so they can understand the part and what they need to do with it. This type of information (shop floor documentation) is created along side design and planning making it easier for the manufacturing staff to use.
As technology advances we are finding that automation in industry is a much more reliable and cheaper way of creating products. Due to it being much faster and there being less human errors, it only seems right that companies are upgrading the machining centres to CNC machining centres.
Automation in a technological sense works on there basic things. Firstly software for the designing and coding of products, secondly are the computers for designers to use the software. The last pieces of equipment are the machines to actually create objects.
Designing software is an evermore growing industry with many different types to choose from. One of the most popular 3D modelling software is Solidworks/CAM.
Automation is nothing without its main tools, the machines. These machines have quite a large spectrum as they range from CNCs, to robotics to Guided vehicles. A good example is the Toyota manufacturing line. It uses man and robotic power. For complicated long procedures a robotic machine will be introduced to lessen the time spent on a process. CNC machines will be used to cut and for materials for the assembly process and lastly the guided vehicles. Toyota have robots that are coded to follow magnetic strips laid on the floor, one it get to one side it will be loaded up with parts i.e. nuts and bolts and will be sent back to the work area. They use robots like these as it means the lead time is reduced dramatically and the work space is larger making it easier to work around products.
