Compared Cutting Speed and Feed Rate in CNC Machining Operation
The computerized numerical control is part of a manufacturing process. CNC deals with codes that control the movement of a tool’s axis. Some programmed principles include; spindle speeds, RPMs, and cutting tool movement. Hence, in any designing process, it’s vital to consider CNC machining operations.
Optimization of different parts of the CNC machining procedure follows the above parameters. Cutting speed gauges power consumption and tool life. Feed rate governs the surface roughness and machining time of finished goods. At Creatingway, we use cutting speed and feed rate in machining. All with the aim of perfecting your project to a required want. Furthermore, below is an explanation of the modes of the manufacturing process.
How To Defining Feeding Rate of CNC Machining Operation?
Feed rate is the distance traveled by a cutting tool in one spindle revolution. Also, it is known as cutting tool engagement in milling operations. The measurement is in minute/inches or minute/millimeters.
Turning and boring operations are measurable in inches/revolution. Any variation of the feed rates depends on a tool and blank material. Some items include; stainless steel, steel, aluminum, and wood. Examples of tool materials are; cement, cutting tool, and ceramic. Some cutting factors like a surface finish also affect feed rates.
To achieve beauty perfection, we rely on the feed rate. Optimizing the process is crucial in the CNC machining process.
What To Consider in The Feed Rate?
Any trait of the CNC machining operation relates to the feed rate. Such a relation ensures safety to productivity, product quality, and tool life. In addition, Below are the factors considered in choosing the feed rate.
-
Surface Finish
Lower feed rates improve the surface finish of a product. A coarse feed rate deals with the rough cut. For instance, If one feed rate of 0.01-0.05mm/rev is used on finishing operation. A rough turning operation uses a degree of 0.1-0.3mm/rev.
-
Machine Tool Capability
A higher feed rate causes high vibrations and cutting forces. The selection of force is chosen according to the capability of a tool. The ability to absorb and transmit high vibrations and forces.
-
Productivity Rate
To achieve a higher productivity rate, we increase the feed rate. This is by losing some of the surfaces’ quality. Keeping the feed rate stable sometimes adds to the cutting speed.
-
The Geometry of a Cutting Tool
The tool geometry affects the surface finish of a product. As a result, If the geometry permits, a higher value of the tool geometry is preferable.
How To Defining Cutting Speed?
The velocity found between the surface of a workpiece and the cutting tool is known as cutting speed. Some major parameters of CNC machining determine the speed surface. For example, they include; cutting temperature, tool life, and power consumption. The values rely on various materials like; aluminum, plastics, and carbon steel. Other procedures like; knurling tools operate under low cutting speeds.
What To Consider in Cutting Speed?
Maintaining an optimum cutting speed brings out a better CNC machining process. The following factors predict the required cutting speed in CNC machining operation.
-
Tool Life
A higher cutting speed wears out the cutting tool materials. Due it softens with every cut reducing the machines’ lifespan. The duration in which a tool works is another factor. To utilize the cutting speed, consider the parameters followed. They include the quantity of produced parts and the tool cost.
-
The Hardness of a Workpiece
Factors that cause material deformity are; scratching, abrasion, and indention. During the machining process, tools quickly deteriorate. Working on more rigid materials requires a slow cutting speed. This is to improve the tools’ lifespan and efficiency.
-
A cutting Tool’s Strength
In machining operations, the strength of a cutting edge is a vital factor. In other words, higher cutting speeds require material made of high-strength materials. Some examples of such materials include; carbon boron nitride and diamond.
Difference Between Cutting Speed and Feed Rate in CNC machining Operation
- During machining, the cutting force is easily influenced by the cutting speed. The speed surface also influences power consumption. The feed rate doesn’t take part in the alteration.
- The measurements of the cutting speed are in m/min. As for feed rate, it’s denotable as mm/min.
- The feed rate changes the flow of the actual chip direction. As for the speed surface, it doesn’t take part in changing the flow from orthogonal.
- A more significant impact is felt on feed rate compared to cutting speed. The feed rate is greater than the speed surface, the tool wear, cutting temperature, and tool life.
Importance of Cutting Speed and Feed Rate
Minimal side effects aren’t visible on softer materials due to space for error. Examples of more delicate fabrics include aluminum and resin. But the results are visible on more rigid materials like titanium due to the limited range of error. They are allowing ample workpiece specifications to refine into a better product. Feeds and speeds easily attain quality surface roughness. We use the two processes to determine the rate at which a material is removable. Also, how much of the material is removable.
