4 Grinding Hub to highlight efficient fine machining processes. Unmanned production, 24/7. For many manufacturing companies, this is one of the key factors for success in this highly competitive field. This has been the case for turning, milling and drilling technologies for some time, but increasingly now also for fine machining.


Combines the characteristics of machining processes, the general formula for CNC machining time calculation of turning, milling, facing and more operations is as below. The machining time here refers to cutting time. T=L/f*N. N=1000*V/π*D T=Machining Time L=Length of cut in mm. N= rpm (revolution of the job per minute)


Both machining and grinding processes follow the basic principle of subtractive manufacturing approach. Here layers of excess material are removed from a solid 3-D blank to obtain final product. On the contrary, in additive manufacturing approach, layer by layer material is added one over another to build a solid 3-D product.

Based on the wear law of abrasive particles with time in the grinding process, the dynamic grinding force model of ultrasonic-assisted single abrasive particle high-speed grinding was established. The model makes the force on a single abrasive grain closer to the real machining situation, which lays a certain foundation for the follow-up study ...

Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...

Machining time Total time consumed by the machine for machining of the job. Machining time depend on cutting speed, depth of cut, feed Machining time =17.75 min 3. Unloading time Time for removing the job from machine Unloading time =1min 4. Miscellaneous time + 2400 + 24000 + 18000 a. Tool changing and re sharpening (5%-10% of machining time)


The operator still needs to set the feed rate, wheel speed and number of grinding passes, but once that is set for each cutting tool the other adjustments are automatic. This dramatically reduces the time needed to program the toolpath and enables the machine to grind large batches of tools with minimal operator input.

Grinding says : Too bad that the cemented carbide tool is so sensitive to coolant. Coolants are a must for abrasive machining for many reasons; one of the principal ones being to keep the work cool. Coolants on high-powered vertical spindle surface grinders provide better cutting action and longer wheel life. This is documented.

Grinding is no exception. So, while Makino machining centers are helping manufacturers cut cost and time by minimizing non-cut time, setup time and tool-changing time, new technologies that combine grinding and milling in one setup in one machine are also reducing part cycle times by as much as 75 percent. Better, faster, more cost-effective.


In the equation of Time for Cylindrical Grinding Cut Length of Cut = Length of job + Over-Travel where, Over-Travel equals to 0.5 cm. And Feed/Rev. = w/2 (for rough cut) or w/4 (for finishing cut).


Increase dwell/spark-out time. Use oscillation (a common practice in plunge ID grinding). Many grinding machines today have variable speed controllers, so changing the wheel's speed can be carried out by simply editing the CNC program or adjusting the spindle speed controller. Other machines might require manually changing pulleys and belts.

In this study, the minimum manufacturing time was chosen as the objective of optimization problem. Also, several grinding parameters containing the initial grinding wheel diameter, the radial grinding wheel wear per dress, the total depth of dressing cut and the wheel life were taken into the investigation.


Cutting speed is the rotational speed of either workpiece or cutting tool (based on which is rotating). It is measured by the unit—revolution per minute (rpm) and designated by N. For example, cutting speed in turning is 295rpm. In case lathe operations, such as turning, grooving, centre drilling, parting, etc., a cylindrical workpiece is used.
