CNC machining used in Toronto made it possible for equipment to use and employ various tools to create something complex without the aid of humans. Because of this, production is now less expensive than it used to be. The number of products manufactured could compensate for the high setup cost, not to mention the more affordable CNC machining employed around the globe including Toronto.
The manufactured parts are guaranteed to be durable, more accurate and can be adapted into any material. CNC machining may cost higher for the first few products manufactured that is why this method is more practical for long-term productions.
In cases of short-run productions, inventors came up with a partial solution to this problem with the use of technologies like selective laser sintering, fused deposition modelling and stereolithography. These processes does not require any human intervention and therefore the first parts produced were less expensive compared to the ones produced using CNC machining. Processes such as laser sintering, fused deposition modelling and stereolithography are only suitable for projects needing only a handful of parts to be manufactured. Despite its benefits, innovation and less cost, it also has some drawbacks. Due to layering, there are steps on the surfaces of the manufactured parts. The bonds used in layering the solids are not as strong rendering the parts produced using these processes not as durable as the ones produced using CNC machining. Its questionable solidity makes it hard to subject to any rigorous testing for functionality. Also, the materials specified might be different from the ones produced. In conclusion, these processes are only less expensive but CNC machining is still superior when it comes to durability and accuracy.
CNC machining can be utilized for prototyping if not for the process of fixturing which is found out to be an expensive process. Another obstacle stopping CNC machining from being used in prototyping is the high processing power required and software codes when doing complex tasks. The software will need to be changed to create a toolpath – loading the original design, choosing the appropriate tools for the job and loading the g-code (these are the codes responsible for directing the machine tools to the right position).
There are a lot of benefits if manufactures chose to employ automated machining in prototyping methodology. CNC machining produces durable parts and is surfaces are smoother than those of made using layered prototypes. Plastics resins and aluminium can be used in the starting process while various other materials can be used after.
