WHY CNC MACHINED PROTOTYPES ARE MUCH MORE EXPENSIVE THAN MASS PRODUCTION PARTS

CNC machined prototypes are the most famous form of prototyping which gives accurate and precise model of the actual product. CNC prototyping allows high production speed and accurate representation of the final product. There is actually a wide range of materials available for CNC machining. The choice of the material used for making prototypes depends upon the properties required in the prototype. The tolerance of the CNC machined prototypes can be varied depending upon the choice of the material.

WHY IS CNC MACHINING COSTLY?

The very first reason to explain the high prices for CNC machining is – tooling is really expensive. This makes volume processes unsuitable for prototyping. The materials used in additive manufacturing often don’t provide the required tolerances. Changing the materials frequently is a time taking process. So, most manufacturers use a single material with the machine. Sometimes secondary processing is required in order to achieve tolerances and get a smooth finish. This secondary processing makes the prototype lot more expensive. CNC machining services setup is a really complex process. A lot of thought and work goes in the setting up of CNC machines. The setup requires various special mills, drills and taps to be properly installed. This obviously increases the cost on manufacturers. Most of the CNC machines use heavy motors of industrial grade. In order to reduce cost all these sophisticated machines need to be used constantly. The process of making  prototypes does not allow the proper use of the machinery as the product is made individually. So you see, this is the major factor which accounts for the high cost of CNC machined prototypes.

WHY IS MASS PRODUCTION CHEAPER?

The mass production of goods is much cheaper due to several reasons. The very obvious reason for this is that much more products can be produced at the same time rather than making an individual prototype at a time. In the process of mass production, highly skilled professionals are really not required to carry out various operations and unskilled labor can do most of the jobs which obviously lead to decrease in labor costs and hence decrease in overall cost. Mass production makes it possible to present sufficiently more products to the buyers in less time. Mass production is faster, cheaper and more convenient than making a single prototype.

COST COMPARISON OF CNC PROTOTYPING AND MASS PRODUCTION

When products are made in mass production process only very few of them undergo the rigorous checking process in which the dimensions of the goods are checked. When a prototype is made, that single prototype is rigorously checked for all the dimensions. This obviously adds to the cost. Mass production makes a lot of products at the same time, whereas rapid prototyping makes only a single prototype at a time. This too increases the cost in rapid prototyping. The sourcing of materials in small quantities is a rather expensive process. Sourcing of materials on a large scale in the case of mass production reduces the cost. Hence mass production is lot more cheaper than the CNC machining of prototypes.

HOW TO HANDLE STEELS OF HIGH HARDNESS ON CNC MACHINING

The competition in the industrial world requires one to constantly come out with the newer, the better, and the more efficient technology which solves the problems of various production processes. Moreover, new materials are being worked with in various production processes, which one would have never imagined could be used for that purpose. In order to put such materials in various applications different methodologies are required.

REQUIREMENTS FOR MACHINING HARD STEEL

Hard materials like S7 steel and H13 steel are many a times required in molds due to their remarkable properties like impact resistance and temperature resistance. Although these hard materials improve the performance of the final products, but these materials require tough machinability. Machining hard materials seem almost impossible for many manufacturers. For machining hard materials one requires – A rigid tool system of high precision, tough and hard tool material, tool holders of high stiffness, proper and appropriate tool geometry and cutting conditions, etc. There is a huge difference in the machining process of hard materials and normal materials used for making molds. Working with hard steels requires the application of the right tools, right strategy and the right technology at right production stages.

TOOLS FOR MACHINING HARD STEEL

The right tools are required by productionists to machine hard steels. Working with hard steels requires one to have all the tool parameters accurately and precisely calculated. It is a must to consider well the sharpness and the edge measurements of the tool.

Square end, ball end and bull nose mills are used at different production stages. The mill with ball end does roughing and finishing operations. The mill with bull nose end is operated on large and flat surfaces. This tool is not so perfect as it gives rise to chipping. The corner parts of the material are processed by the mill with square end. These tools should be occasionally oiled and dry machining should be done with air to maintain their optimum performance.

RIGHT STRATEGIES

Working with hard materials requires the application of right strategy too. For instance, these days hard turning of the parts is done prior to the grinding to the final finish. Grinding process is specifically expensive and needs to be done in accordance with different shapes of materials. Now manufacturers are using various strategies to easily and swiftly turn a prehardened part. Insert selection plays an exceedingly important role in the process of hard turning. Selection of suitable insert is complementary to the process. For materials with much higher ranges of hardness, CBN inserts are used. Wear and tear of tools will necessarily require its maintenance like sharpening and hence the edges of the tool are varied. This variation needs to be accounted in the CAM programming. The best strategy used is the elimination of sharp turns and rather introducing small arcs at the corners in the program. This helps in the machining of corner parts and avoids the wear and tear of the machine. A sudden change of direction by 90 degrees slows down the machine.
