Our country has improved in the machine industry whether it comes from the aspects of tools, technology, or workers. Machine structure fabrication in Malaysia has had its golden times of manual work to working with CNC machines.
Although some parts of the country are still respectfully using the origins of metalwork by manually creating results with manpower, working with CNC machines has its advantages as Malaysians are constantly being introduced to new technologies.
– Manual layouts are required to cut the beam or to drill all holes one by one and step by step.
– The cutting quality is not as satisfactory especially when another operation of grinding must be done.
– The chances of handling damages and accidents are higher as operations of manual materials of handling for cutting and drilling will have to be processed three to five times.
– The time taken for a certain beam size would approximately be 400-420 minutes, that is with the use of a good fitter and cutter.
– The chances of human errors are more as the drawings have to be referred to on the floor.
– While the percentage of components is high in structures, the time taken to prepare the products is long resulting in a delay in fabrication.
– Seventy to eighty percent of the cycle time can be saved as auto measurements are done, as well as automatic cutting and drilling operations.
– Smooth finishes can be obtained as grinding is avoided – accuracy of the machines are achieved up to 0.1mm.
– Cutting and drilling holes for all sides of sections takes place with the beam in one position, therefore no material handling is required.
– The time taken by CNC is approximately 30 minutes.
– Only two machine operators are required to complete the entire operation – for cutting and drilling machines, resulting in a lower man-hour per tonne cost.
– The odds of errors are nearly non-existent as CNC files are obtained directly from the drawing software.
– Mass manufacturing is possible when the percentage of components is large, which helps to reduce fabrication cycle time.
Let’s say you need to increase the number of beams produced per hour, so you buy a multiprocess system that drills, taps, mills, cuts, and possibly even applies layout. It appears to be about as efficient as it gets. However, after the system is up and running, you discover that your cycle time isn’t what it should be. That’s because, once again, adding additional action to the machine’s work envelope lengthens the cycle duration. A sequence of dedicated machines with automated material handling in between, maybe a superior option in this scenario. Smaller structural fabricators, on the other hand, may require the efficiency that a multiprocess system affords.
There are numerous solutions available, but at the end of the day, what counts most is that the company performs more efficiently from a business standpoint: do more with less.
