Chamfer Explained - What is the Purpose of a Chamfer?

Chamfering’s importance is paramount in various fields such as civil engineering, woodworking, and machining. But what exactly is chamfering and what is its purpose? 

Chamfering in Engineering

Chamfering’s importance is paramount in various fields such as civil engineering, woodworking, and machining. But what exactly is chamfering and what is its purpose? 

Chamfer Definition

Chamfering refers to the process of creating a symmetrical edge by removing a right-angled corner or edge. Depending on component size, this may seem like a simple adjustment, but its implications are profound. Especially in industries like aerospace, automotive, etc; where precision is a must.

What is The Purpose of Gear Chamfering?

If parts and gears are left with no chamfer sharp angles can exist, posing a serious risk to operability and safety. These angles become stress points and the component becomes vulnerable to damage and fatigue. In machining, impacts, vibrations, and extreme heat exacerbate these risks and can lead to breaks or fractures. Damage like this can impact the performance of the entire machine. With a chamfer, the stress of the sharp edge is appropriately distributed and the risk of damage is eliminated. 

Reducing Stress with a Chamfer

As an example, consider a 90-degree angle. Chamfering the angle flat and creating two 45-degree angles significantly decreases the stress of that edge. This minor altercation greatly extends the lifespan of components, ensuring durability and reliability.

Types of Deburring

Let’s dive in to eight different methods of deburring!

Punch Deburring

Since its perfection in 1770, sheet metal has become a commonly used material within the manufacturing world. One of the most popular ways of cutting and manipulating sheet metal is a method called “punching”. A punch machine uses interchangeable tools to cut out shapes from the sheet metal, and it’s vital that these tools are sharp. If they aren’t, they require more force to cut through the metal, which can lead to the formation of burrs. Punch machines can deburr the pieces of sheet metal they just cut, and they do so with another set of interchangeable tools, which are meant for deburring. This method of deburring works well for pieces cut from sheet metal, but it’s extremely limited when it comes to parts with complex geometries.

Tumbling Deburring

This method involves parts/gears being tumbled in a barrel full of water and loose materials (known as tumbling media), such as glass beads, steel, or plastic. The force of the material and parts tumbling against each other will break off any present burrs and smooth out a part’s surface. Operators must be able to choose their media correctly, as some will do extreme damage to gears/parts made of other certain materials. For instance, steel parts must be paired with steel material. Tumbling is a good option for larger parts/gears, as it is a quicker way to remove their burrs compared to doing it by hand, and they are less likely to suffer overall structural damage from it. However, that risk is still there, and it can ultimately do more harm than good.

Vibratory Deburring

Vibratory deburring is like the tumbling method in the sense that parts are put into a barrel with tumbling media, but it’s more effective and gentler than its cousin method. When the loose material is vibrated against parts/gears, the force shears off burrs and other imperfections with equal force, making it a safe method for smaller, more delicate parts. This process is used frequently within industries such as the aerospace or medical industries and can even be used for parts made of wood or plastic.

Cryogenic Deburring

The cryogenic deburring method is similar to freezing off a wart. Parts are put into low-temperature chambers, where burrs are then frozen until brittle. The burrs will then get knocked off part surfaces when non-abrasive media is thrown into the chamber. This process doesn’t leave residue and preserves the surfaces of parts of any size. It’s a good option for processing large amounts of parts/gears at once, but it still lacks the precision that is necessary for complex parts.

Hand Deburring

This might be the most common—and the most time consuming—deburring method out there. Workers use handheld tools to manually complete processes such as brushing, edging, chamfering, polishing, and of course deburring. While this method allows for focused precision, workers are limited to working on one part at a time, making it extremely inefficient for high or medium volume shops. These workers also require adequate training and experience, seeing as one mistake can scrap an entire part; a little too much material taken off a part/gear can cause it to not fit into its greater assembly properly and affect its long-term efficiency. Another issue with hand deburring is that consistent chamfers are hard to achieve with it, and chamfers of poor quality will also affect the function of a larger assembly. Some manufacturers still prefer hand deburring to other methods, but it costs too much time and money to be used widely.

Electrochemical Deburring

Electrochemical deburring is a unique method of deburring that shoots currents of voltage between a cathode and a burr, ultimately dissolving said burr. This process can remove any sort of excess unwanted surface material. It’s important to maintain a gap between the cathode and part needing deburring, as this gap (paired with an electrolyte solution) allow for the transfer of voltage. It’s much more precise compared to methods such as punch deburring or tumbling deburring, and allows holes, cross holes, and intersections to be deburred easily. However, this method is limited to a small variety of materials seeing as some don’t contain the required levels of conductivity.

Thermal Deburring

The thermal deburring technique is carried out by placing parts in a pressurized chamber and setting off a series of controlled combustions, which essentially melt off any burrs or surface imperfections. The overall structure of the part/gear in the chamber isn’t harmed due to how momentary these mini explosions are, however the risk of excessive heat damage is still present. Once the burrs are removed, the part/gear is left with a thin film coating its surface and it must be cleared off before it is further processed. While efficient when it comes to removing multiple burrs/surface imperfections at once, it also lacks the necessary precision required by some industries, such as the aerospace industry.  

Machine Deburring

Machine deburring is the most effective method of deburring when it comes to timeliness, cost efficiency, and precision, and has been gaining popularity as the demand for all three of these factors has grown dramatically over the course of the last few years. Machine deburring extends to both CNC machines and finishing machines, such as the MAX System from James Engineering, a high precision deburring and chamfering machine. CNC machines are most efficient when it comes to cutting parts, but they also have limited deburring capabilities. The MAX System and its one-of-a-kind technologies allows the machine to deburr and chamfer, radius, wash, and brush a part concurrently. This is due to its multi-tooling feature, which is customizable to any company’s needs. It also features an 11-axis overhead gantry system, making any angle reachable. The MAX is a great option for both parts and gears of any size and any complexity, and with Focused Deburring (a technology unique to James Engineering), burrs can be targeted—something only James Engineering finishing systems are capable of.

 

Which one is right for you?

These eight methods of deburring are used for a wide range of industries, parts, and gears, and each have their own pros and cons. Finding the right one for your company ultimately depends on the volume at which your shop is producing, and what parts/gears you produce. The lower your shop’s volume is, and the simpler your parts, methods such as hand deburring can be a reasonable choice. If your shop is producing at a high volume and working with a wide array of gears/parts of a variety of materials, a specialized finishing machine such as the MAX System is the most time and cost-effective move to make. Doing your own research is important, and you know your shop’s needs the best… but you can never go wrong with the MAX.
