Pas en Masjienering
Fitting & Machining
‘n Passer en draaier is verantwoordelik daarvoor om planne en sketse te bestudeer om sodoende masjienparte saam te stel, in mekaar te pas en te vervaardig.
Hierdie person is dan ook verantwoordelik daarvoor om masjiene in stand te hou en te herstel.
Draaiwerk is ‘n prosses waar ‘n snygereedskapstuk, hoofsaaklik ‘n nie-roterende gereedskapstuk, liniêr beweeg terwyl die werkstuk roteer.
Draaiwerk kan of met die hand gedoen word deur middel van ‘n draaibank of dit kan gedoen word deur ‘n outomatiese draaibank.
In vandag se tyd is die bekendste tiepe outomatiese draaibank die “computer numerical control”, beter bekend as die CNC masjien.
Wanneer jy ‘n rou stuk material het kan jy dit dan in die draaibank sit en deur middel van die snygereedskap heen en weer sny om die presiese diameter en dieptes op die werkstuk te kry.
Draaiwerk op ‘n werkstuk kan of buite afmetings gesny word of binne afmeteings.
Die prossese wat uitgevoer kan word op die draaibank, wat gesien word as een van die oudste masjien gereedskap, is die volgende tiepes: reguit snywerk, tapse draaiwerk, profile snywerk of skroefdraadsnywerk.
Hierdie prossese kan vir jou ‘n wye verskeidenheid vorms verskaf soos, keëlvorm, kurwes of groewe op werkstuk. Oor die algemeen gebruik draaibanke enkelpunt snygereedskap.
Freeswerk werk op die beginsel van roterende beweging. ‘n Freessnyer draai hier op ‘n as en die werkstuk word dan deer die snyer gevoer wat dan snysels van die werkstuk af verwyder om ‘n snit te voltooi.
Hieride is ‘n rowwe afwerking van ‘n werkstuk wat beteken dat ‘n werkstuk nooit heertemal glad afgewerk sal wees nie al bekyk jy die werkstuk met ‘n mikroskoop, daar sal altyd vyl merkies wees.
Die Pas- en Masjienering kursus is bedoel vir individue wie se pligte insluit om ingenieursmetings, berekeninge, beplanningsaktiwiteite, ‘n reeks snyprosesse, tekeninge en uitmerk, hou aandrywings toestelle in stand, en presisiewerk om draaibanke en freesmasjiene te gebruik.
Moontlike loopbaan geleenthede:
• Meganiese ingenieur
• Meganiese Passer
• Passer en Draaier
• Masjienerings Passer
• Instandhoudings Passer
• Gereedskaps maker
Die werksomstandighede waarin ‘n passer en draaier werk, het veeleisende aspekte.
Is u bereid en in staat om onder die volgende omstandighede te werk?
• Passer en draaiers spandeer baie tyd om te staan, buig en hurk, wat uitputtend kan wees
• Daar word soms van hulle verwag om lang ure te werk, ook gedurende die nag en gedurende openbare vakansiedae.
• Die werksomstandighede kan dikwels lawaaierig, vuil, druk en gevaarlik wees, wat beteken dat daar baie aandag aan en bewustheid van veiligheid nodig is.
A fitter and turner is responsible for studying blueprints, plans, and drawings to be able to construct, assemble, manufacture, and fit parts of machines.
This person is also responsible for maintaining and repairing different types of machinery.
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, moves more or less linearly while the work piece rotates.
Turning can be done manually, in a traditional form of lathe, or by using an automated lathe.
Today the most common type of such automation is computer numerical control, better known as CNC.
When turning, a piece of relatively rigid material is rotated and a cutting tool is traversed along axes of motion to produce precise diameters and depths. Turning can be either on the outside of the cylinder or on the inside (also known as to produce tubular components of various geometries.
The turning processes are typically carried out on a lathe, considered to be the oldest machine tools, and can be of four different types, namely straight turning, taper turning, profiling or external grooving.
These types of turning processes can produce various shapes of materials such as straight, conical, curved or grooved work pieces. In general, turning uses simple, single-point cutting tools.
Milling operates on the principle of rotary motion. A milling cutter is spun about an axis while a work piece is advanced through it in such a way that the cutters are able to shave chips of material.
This non-continuous cutting operation means that no surface cut by a milling machine will ever be completely smooth; at a very close level (microscopic for very fine feed rates), it will always contain regular ridges.
The Fitting and Machining pathway course is for individuals whose duties include performing engineering measurements, calculations, planning activities, a range of cutting processes, use drawings and mark out, maintain drives, and precision work, use lathes and mills.
Possible career opportunities for graduates include:
• Mechanical Engineer
• Fitter Machinist
• Fitter and Turner
• Mechanical Fitter
• Maintenance Fitter
• Tool and Die Maker
The working conditions that a fitter and turner works in have demanding aspects. Are you willing and able to work in the following conditions?
• Fitters and turners spend a lot of time standing, bending, and crouching, which can be tiring.
• They are sometimes expected to work long hours, including during the night and over public holidays.
• The working conditions can often be noisy, dirty, crowded, and dangerous, meaning a lot of attention to and awareness of safety is needed.
