Many industrial applications require the use of a CNC machining system. This system plays a significant role in supporting accuracy in manufacturing. The cost to run a CNC machine is dependent on several variables, from project length to the different machine parts required. Engineers are always looking for ways to keep production costs down, and CNC machining is no exception.
Try To Avoid Deep Pocketing
The production costs increase any time an excessive removal of material is necessary. The removal process is time consuming and requires using special tools for accuracy. By limiting and avoiding this function altogether, you can significantly impact machining costs and reduce time constraints.
Expand Wall Thickness
It might seem like creating a thin wall is relatively affordable since there is less material, but the accuracy required to produce these specifications is significant. These walls are more fragile and more prone to fracturing or errors. Expanding the wall thickness creates a more durable product and reduces the costs of the machine.
Put a Limit on Thread Length
A thread length beyond 1.5 times diameter is unnecessary and increases costs in several small ways, typically because of the parts necessary to accommodate the measurements. These additional parts and costs will tack on to existing production costs. By reducing the maximum thread and the length allowed, you can minimize additional costs and increase the overall efficiency of the threaded assembly.
Avoid the Use of Multiple Finishes
Similar to how the unnecessary length of a thread can induce rising costs, using multiple finishes can have the same effect. The best way to keep CNC machining costs down is to leave the finished part as is and avoid additional finishings. The existing finish helps protect a part in harsh conditions and maintains the appearance of a part.
Split Up Complex Parts
You will need additional machining parts to produce a part with any complex geometrical requirements. Specifying a reposition or rotational need or creating custom fixtures all come with a cost, increasing overall CNC expenses. You can use a singular geometric measurement to produce individual components by splitting up complex parts production into multiple sessions.
In general, the common denominator to keep costs down is to maintain a simple production operation. When things become too complex, costs begin to rise. Ensure your production process is straightforward and minimize the number of accommodations.
