ENGINEERING FITTING SKILLS TRAINING COURSE

COURSE 780: 3 DAYS: Max 4 Candidates

This course provides candidates with the opportunity to acquire essential workshop bench skills. The candidates fabricate a practical project, using hand tools and pillar drills. The project requires the reading of drawings, marking out, sawing, filing, drilling and tapping and these skills are taught as the candidates progress through the project.

The proper and safe use of tools coupled with the necessity to fabricate to the tolerances specified in the drawings ensures that the candidates improve their practical bench skills and also learn how to apply themselves to the exercise most effectively.

PARTICIPANTS

The course is designed to complement course 700: Mechanical maintenance skills and is suitable for craft personnel already involved in maintenance activities.

COURSE PRESENTATION

One of the practical exercises on the engineering fitting skills course - learning how to sharpen drills properly

The course format is very much 'hands on' - the emphasis being on development of sound practical skills within the context of safe working practices.

COURSE OBJECTIVES

On completion of the course, participants will be able to

Successful completion of the course leads to the award of the Technical Training Solutions competence certificate 780: Engineering Fitting Skills.

What do candidates on the Engineering Fitting Skills course actually do?

The Engineering Skills course begins with a brief reminder of the Health and Safety issues of working in an engineering workshop. Candidates are then shown how to use a range of measuring instruments such as steel rules, vernier callipers, micrometer and dial gauges. Practical exercises have been prepared that require the candidates to determine various sample vernier readings, proving that the instruments are being interpreted correctly.

Engineering drawings are viewed and evaluated to determine which system of drawing projection has been used (first angle or third angle). The following are some example pages from the course notes for this stage of the engineering fitting skills course, describing how scribing blocks are used to mark out accurately, how engineering drawings depict mechanical components in the various projections and how holes should be marked out for accuracy:

This leads on to a number of marking out exercises on aluminium and silver steel components. We use dividers, scribing blocks and callipers (amongst other tools) for this.

Metal components have to be cut and filed using hand tools to produce datum edges. We use scribers, punches, saws, hammers and files (amongst other tools) for this.

The drawing for the V Block

Holes have to be accurately marked out and later drilled and tapped with metric threads.

After assembly of the manufactured components, some holes have to be reamed to ensure a good engineering fit to ground steel locating dowels.

The object of the exercise is to produce a test piece that the candidates can use in the workplace for shaft alignment.

The manufacture of the alignment tool test piece will take several hours to complete, and brings into play the interpretation of drawings and the hand tool skills previously gained.

Some candidates progress further than others through this exercise. The V Block shown here has had some additional parts manufactured for it which candidates that make a lot of progress have the time to do.

However all candidates must produce a finished item that complies with the diagram.









While the candidates are completing the test piece, they are given other projects to complete such as thread identification and an exercise in applying the correct tightening torque to flanged joints. Candidates are kept extremely busy due to the intensely practical nature of this part of the course.

The following are some example pages from the course notes for this stage of the engineering fitting skills course, describing the common screw threads encountered on industrial machinery and how drive shaft keyways should be fitted:

Candidates are given the opportunity to sharpen drill bits so that they gain an appreciation of the importance of the various angles etc, as well as an appreciation of how the pedestal grinder should be used.


The final exercise is an opportunity for candidates to learn the fundamentals of drill sharpening: a valuable experience to enable a better understanding of how rake and clearance angles on a twist drill affect the finish and accuracy when drilling through different materials.
