Economic Benefits of CNC Machining

CNC Machining versus conventional machining 

Conventional machining requires a skilled operator to manipulate the machine tool handwheels to produce a determined component. The Operator has to examine the drawing many times, during the operation, to determine the dimensions that apply and must decide by how much each handwheel must be turned to produce the desired result.            

Many conventional machine tools have speeds and feeds governed by mechanical design features such as fixed-speed gearboxes. Thus the choice of feed or speed is a compromise depending on the gear ratios built into the machine tool.

By contrast, CNC machine offer complete control of all axes, under optimum cutting conditions. Extremely short set-up times are possible since standard tooling is all that is required. The good accuracy and repeat ability of the components produced by CNC machines enables a greater uniformity of production. The quality of finished job is no longer under the control of the operator but under the control of a computer-run part program. 

Adopting CNC

CNC provides for an automated approach to manufacturing. To change from one type of component to another requires only a minimum amount of set-up time and the provision of a part program. The main reasons to adopting CNC can be listed as follows:

·         CNC provides flexible automation, adaptable to many differing requirements, and changeovers from one job to another are rapid.

·         The Investment of time in producing part programs can be realised many times over since repeat orders require no additional work.

·         CNC offers reduced downtime, early production start-up, uniformity of production, minimum machining times, and less scrap and re-work.

·         CNC can reduce labor costs.

Drawback of CNC

The biggest single limitation is probably the initial high capital cost of the equipment itself and its sub sequence installation. CNC equipment is also high technology equipment and will require maintenance of the different nature to that conventional machine tool.

The introduction of CNC machine will inevitably lead to the loss of existing conventional machines and their operators. Resistance to change may further hamper the introduction of CNC. Planned alternatives for those members of the workforce unable to make the transition into CNC operation must be carefully considered.

4 Advantages of CNC machining your product

There are numerous advantages CNC machines have over traditional manual manufacturing, and these are just some of the reasons we use them.  

1. CNC machines can run for 24 hours, 7 days a week and all year round and need minimal  maintenance which is one of the only times our machines need to be turned off.

2. If you want an updated systems, sometimes it’s as easy as just updating the coding software.  This means you’ll get a state of the art product as new manufacturing procedures are developed.

3. Unlike manual labourers CNC machines can work repeatedly and consistently while still producing the same result.  CNC machines are made to manufacture things thousands of time so they don’t get tired.

4. With a little bit of training, operating CNC machines is quite simple which leaves time trained and skilled engineers to improve on other aspects of design and production.

Getting the right product finish

Machinists utilise their skill and expertise to produce the most aesthetically pleasing and accurate components possible.  They take pride in their work as do their clients.  A good surface finish and the general look of parts are very important aspects which require the most ideal machining practices to be used.  So how do machinists get the results they want? The following is by no means extensive but it give a little insight:

Use an insert with a wiper

If you can, make sure your manufacturer uses an insert with a wiper.  These have a flat section like the second image in the diagram above.  This flat part ensures that the surface is wiped smooth as the tool moves across the outside of the part.  You can also avoid a finish that has thread elements to it.

Increase the speed

When using cutting tools a rise in the speed of the tool will make sure that your part is touching the tip of the tool for a smaller time period.  This minimizes the material build-up on the end of the tool which can in turn make the surface finish less than ideal. 

Reduce pauses

When a tool stops while it is still touching the surface it can leave a mark on the part.  If you make sure to minimise the number of pauses and hesitations of your tool you can ensure a better surface finish.  You may need to change the entire manufacturing procedure.

Cnc Machining Advantages

CNC Machining - ALNO

1. CNC machines can be used continuously 24 hours a day, 365 days a year and only need to be switched off for occasional maintenance.

2. CNC machines are programmed with a design which can then be manufactured hundreds or even thousands of times. Each manufactured product will be exactly the same.
 
3. Less skilled/trained people can operate CNCs unlike manual lathes / milling machines etc.. which need skilled engineers.
 
4. CNC machines can be updated by improving the software used to drive the machines
 
5. Training in the use of CNCs is available through the use of ‘virtual software’. This is software that allows the operator to practice using the CNC machine on the screen of a computer. The software is similar to a computer game.
 
6. CNC machines can be programmed by advanced design software such as Pro/DESKTOP^®, enabling the manufacture of products that cannot be made by manual machines, even those used by skilled designers / engineers.
 
7. Modern design software allows the designer to simulate the manufacture of his/her idea. There is no need to make a prototype or a model. This saves time and money.
 
8. One person can supervise many CNC machines as once they are programmed they can usually be left to work by themselves. Sometimes only the cutting tools need replacing occasionally.

 

9. A skilled engineer can make the same component many times. However, if each component is carefully studied, each one will vary slightly. A CNC machine will manufacture each component as an exact match.
