There are many kinds of CNC machining processes, so it is often necessary to estimate the time of one or more operating procedures. These are related to the CNC machining cost of the parts and the on-time delivery time. The calculation of the actual CNC machining cycle time is usually more than the formula calculation. complex. Below we show you how to calculate the milling machining time in actual processing.
How to Calculate the Cycle Time of CNC Machining,Turning, Milling, Etc.?
CNC machining distance or length divided by speed or rate is the most basic rule. According to different process characteristics, the general formula for the time of multiple processes such as turning, milling and end face is as follows: T=L/f*N, N =1000*V/π*D
Note: T=processing time, L=cutting length (mm), N=rpm (operation revolutions per minute) V=cutting speed, unit mpm (m/min), D=rod diameter (mm), f=in Give amount mm/rev (mm per revolution))
Calculation of Machining Time for CNC Turning
Turning is the process of producing turned parts on a lathe with a single-point tool. When calculating or estimating the CNC machining cycle time of the turning process, the formula is also based on T=L/feed*N, L or length=(tool approach + working length + tool overtravel)*No. In the pass, N refers to the average RPM, which is equal to 1000*cutting speed/π*average diameter.
CNC Milling Machining Time Calculation
CNC milling is a machining technology that can process various cross-section grooves or ribs, vertical, horizontal and inclined planes, rotary surfaces, spiral grooves, etc. For milling operations, the feed rate may be in units per tooth, which means you need to know the number of cutting edges, teeth, or grooves on the tool. According to L=working length+tool approach+tool overtravel+forced distance, f=feed per revolution=feed per tooth*number of teeth, N=1000*cutting speed/π*D, enter the formula T=L/f* N calculates the milling time.
