Gensun Precision is a leading provider of CNC machining services across Asia.
However, even after you choose the ideal cutting speed and feeds, the success of your project also depends on the machine shop you work with. cutting speed, you’d agree that these two machining parameters are important during CNC machining.
Now that you understand the differences between feed rate vs. CNC Machining with Gensun Precision Machining Doing this helps to improve your productivity and tool life. One way to reduce the effect of chip thinning is to machine your workpiece at high feed rates. This reduces the chip load (the size or amount of material removed by the cutting tool per revolution), causing greater lead times. Learn More About: CNC Machining Materials Chip Thinning and Optimum Feed RateĬhip thinning is a manufacturing defect that occurs when you machine a workpiece such that the cut width is less than half the diameter of the cutting tool width. Table 1 presents some of the common cutting tool materials and their allowable cutting speed range. For example, you can use high cutting speeds when machining with a cutting tool made of high-strength materials like diamond and carbon boron nitride, whereas tools made of high-speed steel demand lower cutting speeds. The strength of the cutting tool plays a role in the allowable cutting speeds for machining operations. For example, materials like titanium will require a lower cutting speed compared to steel. Harder workpiece materials demand special attention during machining since they can easily reduce the performance life of cutting tools.Īs a rule, the harder the workpiece material, the slower the cutting speed you should implement during machining. Hardness describes the resistance of a material to deformation induced by abrasion, indentation, or scratching. To determine the optimum cutting speed for your machining project, you need to consider the workpiece hardness and the strength of the cutting tool. Instead, feed rates are more likely to affect the machining time and surface finish of the machined part. Similarly, cutting speed affects the tool life, cutting temperature, and power consumption.įeed rates also affect the tool life and power consumption during machining, but their effects are usually negligible compared to cutting force. This wear is due to the friction and high temperatures between the tires and the road.
Still considering the car analogy, a wheel rotating at higher RPMs will likely consume more power and wear more quickly than wheels turning at lower RPMs. We measure it in inch per revolution (inch/rev) or millimeter per revolution (mm/rev). Feed rate is simply the distance the tool travels during one revolution of the part. In contrast, we can compare the feed rate to the wheels’ rotation in the car analogy. Cutting speed is measured in millimeters per minute (mm/min), meters per minute (m/min), or feet per minute (ft/min). It measures the linear distance moved by the cutting tool against the machined part at a given time. But when describing the vehicle’s speed to a friend, you’d explain it in terms of kilometers per hour.Ĭutting speed can be compared to the linear velocity of the car, which depends on the wheels’ diameter and RPM. You’d agree that the wheels’ diameter and rotation are responsible for the car’s movement along a paved road. To help you understand these two terms, let’s consider a simple analogy of a car moving at a linear speed of 60 km/hr with wheels rotating at 500 rpm.
