Unit 4010 Mechanical Workshop Practices Assignment Brief

Introduction

The complex and sophisticated engineering manufacturing processes used to mass produce the products we see and use daily has its roots in the hand-operated lathes and milling machines still used in small engineering companies. To appreciate the fundamentals underpinning complex manufacturing processes, it is essential that engineers are able to read engineering drawings and produce simple components accurately and efficiently.

This unit introduces students to the effective use of textual, numeric and graphical information, how best to extract and interpret information from engineering drawings, and the practices of workshop-based turning and milling machining.

On successful completion of this unit students will be able to learn about the mechanical measurement and quality control processes to analyse the dimensional accuracy of a machined component; operating machining equipment to produce a range of components to specification; the importance of material selection when choosing the most appropriate machining process; and application of safe working practices throughout.

Learning Outcomes

By the end of this unit students will be able to:

LO1 Discuss the potential hazards that exist when operating machine tools and bench fitting equipment, with reference to the appropriate health and safety regulations and risk assessment criteria

LO2 Produce dimensionally accurate engineering components through operating a manual lathe and milling machine

LO3 Interpret information from engineering drawings to operate measuring tools and work-holding equipment to check dimensional accuracy of machined components

LO4 Explain mechanical measurement and quality control processes.

Essential Content

LO1 Discuss the potential hazards that exist when operating machine tools and bench fitting equipment, with reference to the appropriate health and safety regulations and risk assessment criteria

Safety compliance:

• Importance of, and responsibility for, safe working practice
• Safe working practices when operating machining equipment in the mechanical machine workshop
• Safe working practices when performing workshop fitting activities, e.g. using hand tools for marking out, sawing, filing, drilling, tapping and assembling parts
• Consider the implications of waste produced by the workshop process, relating to environmental and health and safety issues
• Workshop safety legislation and regulations, and how they are met in practice
• Risk assessment of bench fitting and machining activities
• Discuss in groups a range of industry case studies involving hazards and mitigation measures undertaken.

LO2 Produce dimensionally accurate engineering components through operating a manual lathe and milling machine

Operation:

• Factors influencing machining operations
• Set-up and use of a manual lathe and milling machine following all safety procedures
• Most appropriate cutting tools, work and tool holding methods for multiple applications
• Speeds and feeds to suit material properties (e.g., metallics, non-metallics/composites/plastics) and application
• Use of work-holding jigs and fixtures
• Removing material within dimensional tolerances.

LO3 Interpret information from engineering drawings to operate measuring tools and work-holding equipment to check dimensional accuracy of machined components

Drawings function:

• Types of engineering drawing and their use
• Developing proficiency in reading and extracting information from mechanical engineering drawings
• Types of measuring tools
• Characteristics of measurement tools for inspecting parts
• Preparing quality control and inspection reports.

LO4 Explain mechanical measurement and quality control processes

Control processes:

• Types of production quality control processes, metrology techniques
• Importance of quality checks on machined components
• Function of quality control metrology equipment, including CNC controlled coordinate measuring machines, mobile measuring arms and touch probes, contact scanning probes and non-contact sensors (optical)
• Importance of the process for data collection, analysis and product improvement.
