hi could you please help me producing a report for HNC level of Mechanical Engineering as per below:
Scenario
You work as a project engineer for a tier supplier to the aerospace industry who manufacture machined components for the aerospace industry. Your company has had D solid modelling CAD systems and CNC machine tools for some time but the two are used independently of each other. The design engineers produce detail drawings and the CNC programmers use the drawings to program machine tools.
From your woark at university, you recognise the productivity benefits from an integrated CADCAM system and have suggested your ideas to the Production Directror who has agreed in principle but would like you to prove your theory.
The production director has asked you to investigate the requirements, prove the system and produce a report analysing the benefits and detailing the requirements of a fully integrated CADCAM system, if your ideas are proven to be beneficial to the company, your report will be shared with all technical and nontechnical directors and should be written in a way that is readily understandable by all regardless of theis specialism.
The report should:
You should produce a structured report which provides a critical evaluation of a CADCAM system and its effetiveness in producing a solid model and enables the CAD model to be transferred to a CAM system for the manufacture of the component using a CNC machine centre.
Uding ilustrative exemples, you should also provide a critical evaluation of the way machining conditions and specifications, such as specific dimentionsgeometrical tolerancing and surface finish impact manufacturing.
The report should include the following:
Explaig in different methods of:
a Component setup
b Workholding
c Tooling
On a CNC machining centre milling
Describe the hardware and software that the company is likely to need for an integrated CADCAM system. Your report should include the typical specification of the hardware required.
Assess the importance of the following geometry manipulation methods on efficient model production;
Constraintsgeometric relationssmart dimensions
produce a flowchart describing with examples, the inputs and outputs of the CADCAM process.
Provide a readily understandable analysis of the suitability of the following methods of programming CNC machines:
Manual programming using machine code
Conversational programming on the machines control panel
The use of CAM software
The use of CADCAM software
and a critical evaluation of the effectiveness of using a CADCAM system and solid modelling to manufacture components
