CNC machining process parameters

Technology is changing swiftly and with the change in technology comes modern inventions and innovations in every field. These innovations make the things easier and perfect for mankind. Manufacturing is one such arena where the new innovations are making the production a seamless activity. One such technology in manufacturing is CNC machining.

CNC machining is a process of manufacturing in which pre-programmed computer software dictates the movement of factory tools and machinery. In other words it is a metal fabrication method where written code controls the machinery in the process of manufacturing.

The CNC machine process comes with many benefits in the form of improving accuracy, helps to boost safety and the volume of production, creates flexibility in the manufacturing and ensures consistent product quality.

When choosing a good CNC machining services in Canada, it important to take into account the following points:

Good knowledge: It is important that a CNC machining service provider that you choose should have a thorough knowledge of varied aspects of CNC machining. They must be aware from all the aspects right from the product designing to prototyping and manufacturing. Also, they should know their way around the variety of CNC equipment so that they can advice the perfect CNC machines in sync with the budget and product of the client.

 Experience: With experience comes expertise. The good CNC machining services must have experience in varied industries and should be aware of the cutting edge trends in manufacturing. This is important especially if your product is new so that the company can recommend the perfect manufacturing strategies. Check their portfolio and see if their work profile to see if they can work on short term and long projects as per your product needs.

Flexibility and precision: Manufacturing with accuracy is one of the more important aspects in the success of the product. It is important that you choose the CNC service provider who takes care of every minute detail of shape, specifications, size and material used when manufacturing. An ideal CNC service provider must also work in sync with you and quickly adapt the changes that are advised by you. In other words the service provider must have flexibility in handling the concerns of the client.  They efficiently manage the raw materials and product designing on their own.

Location: Next important aspect to look for when picking a CNC machine service company is its geographical location and how close it is to your own company. Having a CNC service provider nearby reduces the costs of logistics and makes it easier to communicate quickly and easily. It is therefore advisable to pick the CNC service provider within your locality as it minimizes the risk of damage to your product during the transportation.

Added services: A good CNC service provider has something extra to offer like metal fabrication, custom machining, scale model prototyping and many more. And with their extra services you can save money and time on those instead of going with varied vendors for every service.

An ideal CNC machining service provider should save your time, efforts and money apart from deliver you complete and hands-on manufacturing solution.

10 Tips for Better Surface Finish For Your CNC Machining Parts

There are several things we need to keep in mind in order to get a perfect CNC machining part. Some of these major pointers come before we begin manufacturing them, like correct dimensions and tolerances, shape, quality of the raw materials used etc. But there is something that needs to be worked on after the machining part is produced.

Surface Finish: A process that helps define and refine the overall texture (lay, roughness, and waviness) of the machining part. We just cannot ignore the importance of an impeccable surface finish.

How to ensure the steps we are adopting will get a better surface finish? We understand your dilemma. Hence, we have created a checklist of major surface finish that will help you make your CNC machining parts better.

1. Increase Your Speed

This really applies most when using carbide tools. When you increase the surface feet per minute speed (SFM), you will ensure that the material is in contact with the tool tip for a shorter amount of time and will also reduce edge buildup on the tool, which causes poor surface finishes.

2. Reduce Your Feed Rate

Reducing the feed rate helps to improve surface finish. This will also help to reduce flank wear and prolong the insert’s longevity. In addition, doubling the nose radius will help to improve surface finish. For roughing applications, it’s best to use a tool capable of a high feed rate to remove material quickly. For finishing, it’s best to have a lower feed rate and shallower cut.

3. Increase the Top Rake Angle

Positive rake angles will lead to a finer surface finish, requiring lower cutting forces. Using a 45° cutter will act downward, possibly making the part flex. As a result, this will cause the back half of the cutter to recut the machined part and create a poor surface finish. Using a 90° cutter will create cutting forces parallel to the part and will not flex it. This will produce a smoother surface finish.

4. Use a Chip Breaker

A poor surface finish can also be caused by improper chip breaking, downtime to remove chips and higher temperatures at the tool’s cutting edge. A chip breaker can produce smaller chips that are cleared from the cutting area quickly. And because there is no longer a need to clear chips by hand, safety is improved.

If the chip breaker can break the chips into adequate lengths, then vibration will be minimized; the chips will not wrap around the workpiece and tools will not be damaged. Chip breakers also reduce cutting resistance, which can avoid chipping or breaking the cutting edge. A lower cutting resistance can decrease heat and delay tool wear.

5. Use a Large Nose Radius

The idea is to use a larger nose radius and decrease the feed rate to get a smoother, finer surface finish. This is because the nose radius and depth of cut affects the shape and direction of chips. Therefore, it’s best to use the largest radius possible to achieve the best surface finish and avoid creating chatter (machine vibration). But, on the other hand, a larger nose radius will increase demands on the tool, causing vibration and poor chip breaking, whereas a smaller nose radius produces thinner chips that are easier to clear away from the workpiece, but this will also limit the feed rate.

6. Use an Insert with a Wiper

To ensure a good surface finish, use a special wiper insert that has a modified nose radius with larger corners to wipe the surface smooth. This will allow you to cut at a faster feed rate.

7. Use the Right Technique

Creating a chip that is thick-to-thin is what you want. Your technique plays a vital role in getting smooth surface finishes. Choose a cutter that is smaller than the nose radius so you can program it for a smooth transition from line-to-line.

When you run your final cuts, don’t just limit yourself to checking your workpiece; you should also read your chips. The characteristics of your chips will indicate what machining set up or tooling adjustments are necessary.

8. Use Different Tools for Roughing and Finishing

Some may say that the same inserts can be used for both roughing and finishing. But it’s best to use separate inserts, one for roughing and one for finishing. For roughing, you can use a course-pitch cutter with a large nose radius, and a large rake angle with a rapid feed rate. For finishing, you can use a fine-pitch finishing tool with the proper lead angle and a wiper flat, which will give you a better surface finish.

9. Clear the Chips

There is a debate whether to use coolant in milling applications. But it all depends on the type of work you’re doing, such as deep cavity milling, the type of material and which insert you are using. Using coolant, in some cases, should be avoided. It may cause thermal cracking and shorten tool life and could affect the surface finish negatively. But with aluminum, low-carbon steel or nickel-based alloys, using coolant will prevent the tool from sticking to the workpiece.

10. Check Your Toolholding and Workholding

It’s a good idea to check the condition of your toolholder. An old, worn-out toolholder may cause the insert to move. This will cause chatter and will negatively affect the surface finish of your part. You also want a rigid workholding that is stable, especially with a higher metal removal rate.

All these tips are from our 20 years of experience in the cnc machining parts and cnc machining services field. It helped us, it might help you too. So, go ahead and adopt these practices so you get a perfect surface finish.
