Possible Solutions Created:

• Teenut and Slot tolerance reduction
• Side plates to the sides of the Sliding Jaw
• Alternative Dovetail to Slot on Base plate

The 2800 Vice's obstacle to efficiency consists in the difficulty in motion in the Sliding Jaw area, where the issue lies that the movement is not in place and loose. This presentation will help in communicating how to solve this issue.

What is the 2800 Vice Problem?

01. Justification

Looking further into these inital steps, they would mould a way to find a solution to the problem provided. So, the aim of this powerpoint is to convey the process that was taken to find the remedy for the 2800 Vice problem and completing the objective.

To begin, the general objective desired is to either reduce or eliminate this excess of movement and the basic steps are as so:

Aims:

• Mindmap Ideas to Possible Solutions
• Sketching, Developing and Finalising

• Creating Engineering Drawings
• Looking at Infomations resources
• Concluding a resolution

General Process:

02. Objectives

+ info

As stated in my Engineering Report, a mindmap is the most efficient way to begin a process as it allows creativity to branch out and that is how I began the initial framwork in outlining the possible ideas that could help resolve the problem. This way I was able to acheive a starting point to the process.

How the process began:

03. Theoretical Framework

+ info

To further develop the ideas generated, Sketching allowed me to visualise and expand on the initial designs I planned on the Mind map.

Expanding on these Ideas

H1

• H1 - Teenut Tolerance
• H2 - Dovetail Slot
• H3 - Sliding Jaw side plates

After developing the 3 Ideas through statistical data and drawings, I had to then choose one to take forward which had to ultimately solve the issue.

Finalising an Idea

05. Hypothesis

+ info

After developing and looking at the pros and cons of the ideas, the idea I thought would be most suitable and effiecent was the Teenut modification.

Choosing an Idea

04.1 Development

+ info

The next step I took into the Teenut concept was the changes that needed to be made for the Tolerancing which was done by researching information.

Researching Sources

04.2 Development

Comparing sources, the information collected from the books tended to be more stastically accurate due to the various checks they undergo when publishing, especially with books that contain numerical data like a Zeus Book and Engineers Blackbook. Overall, going through these sources and cross-referncing between them both allowed me to get a wide and collective gathering of information in regards to the Limits and Fits required to produce the perfect fit for the Vice. The information provided included Clearance decriptors, Diagrams, Statistical Data, Tables, Shaft and Hole tolerances and more.

Apart from the numerical data gathered from both sources they also provided descriptions and diagrams

When cross-referrencing to the sources online, a similar outcome was recieved although it could be seen as less reliable.

Online source comparrsion:

After looking at the evidence gathered the Sliding Fit was seen as the most suitable as collected from the offline sources.

Which was the most suitable?

06. Methodology

Therefore, the results extracted were that:

• The Sliding Fit (Hole - H7/g6 and Shaft - G7/h6) tolerancing would be the appropriate fit to be applied on the Teenut and Slot
• Using this would help to overcome the movement issues in the 2800 Vice and implement movement strictly to the direction intended within the sliding region
• The next steps now would be to implement these results into a working piece and manufacturing the new and improved part with the tolerating applied.

What were the Final Results?

07. Results

Finally, the outcome was achieved and hopefully this presentation proved the effectiveness of both manual and online sources and going through the gradual development process. To conclude, these results can now be put into place and then tested for further feedback and development.

Was the objective achieved?

08. Conclusion
