Despite developments in various technologies, CNC machining remains one of the most cost-effective solutions for on-demand production to date. Its value in cutting metals and other hard materials is undeniable. This article will shed light on the many considerations made by machine shops when estimating prices. It will also provide practical advice on how to minimize these expenses.
The Costs of CNC Machining and Related Elements
CNC machining is one of the most economical on-demand manufacturing techniques for producing precise parts, particularly different metal parts with great physical qualities. Although this method of producing parts has been around for a while, technological developments have lowered the cost of CNC machining so that it is now more affordable for manufacturers. Let’s examine the various elements that affect how much a CNC-machined product costs.
- Part Complexity and Design
You must first consider how difficult the part will be to make. The shape and design of the part can greatly impact how much it costs the machine. A part’s manufacturing cost may increase as it becomes more sophisticated.
- Production Volume
This is one of the aspects of machining costs that is most widely recognized. The cost-per-part would decrease as the amount of the produced part increased. The shift to high mix, low volume production, which requires machine shops to produce a wide range of goods in discrete quantities, poses a significant problem in this situation. These procedures will undoubtedly raise the cost of machining.
- Types of Materials
Costs for various materials vary. When comparing pricing per block, a basic block of stainless steel will undoubtedly be less expensive than a more sophisticated alloy like Inconel. Aluminum, Stainless Steel, Brass, and even Titanium alloy are some common materials used in machining. The degree of machinability and cost will vary depending on the material you choose.
- CNC Machine Related Costs
A CNC machine tool’s effectiveness, adaptability, accuracy, and longevity are key factors in machining costs.
- Cost of Programming
Because of the complexity of CAD/CAM and the need for specialized people to design and digitalize the necessary part, programming is frequently expensive. A designer who created a CAD (Computer Aided Design) file for the product must receive it first. The manufacturing engineer would then need to determine whether the design can be produced effectively and offer recommendations to increase its machinability. A programmer must convert the CAD data into a CAM file, which will be fed into the CNC machine.
- Cost of setup, transition, and processing
Time is money in the industry. The cost of your machining process increases with the amount of time it takes to make an item. A Production Engineer is frequently needed for set-up costs as they must ensure that everything is prepared before the first batch of items can be manufactured.
- Quality Costs
Quality expenses are related to avoiding, discovering, and resolving difficulties with products related to quality.
- Opportunity Costs
These are frequently hidden from the manufacturer, but they impact your machining processes’ profitability.
Any of the following may be considered opportunity costs:
- Costs of utilities, space, labor, training, and other factors
The price of power, water, garbage disposal, cleaning, space, and other continuous operating expenditures must also be considered. If your machine shop is open 24/7, these costs could be significant. Not to mention the number of operators required for each process.
