CNC machining itself is to achieve automation, liberate manpower, improve work efficiency, and improve the quality of the workpiece. How to ensure the high efficiency of CNC machining? The following answers for everyone:
On the premise of guaranteeing the smooth running of the machine tool, the method that can shorten the time of acceleration and deceleration is the best solution to increase the speed of CNC machining, and is also the most critical issue in the study of acceleration and deceleration.
In general, there are two different acceleration and deceleration control schemes: pre-interpolation and post-acceleration and deceleration: the acceleration and deceleration control before interpolation and after interpolation preprocessing are generally called pre-acceleration/deceleration control, after interpolator and servo control. The feedrate for controlling the motion axis before the device is generally called post-acceleration. After the acceleration and deceleration control algorithm relative to the front acceleration and deceleration is relatively simple, do not need to calculate the deceleration point, but the servo gain of different axes is not the same, easily affect the accuracy.
Therefore, the current domestic CNC machining is generally used before the acceleration and deceleration control technology, acceleration and deceleration control methods can be attributed to the soft acceleration and deceleration method and the traditional acceleration and deceleration method, the traditional acceleration and deceleration methods trapezoidal acceleration and deceleration method and index acceleration and deceleration methods Methods: Flexible acceleration and deceleration methods include trigonometric acceleration and deceleration, S-curve acceleration and deceleration, and polynomial acceleration and deceleration. The traditional trapezoidal and exponential acceleration and deceleration affect the smoothness of motion due to abrupt acceleration, and the soft acceleration and deceleration have received much attention in high-speed metal processing due to continuous acceleration 3. When removing the tool, do not directly hold the blade of the tool by hand to avoid being cut.
4. During the machining of precision parts, the operator must not observe the cutting state too closely to prevent the chips from entering the eyes.
5. The tools to be used should be placed in the designated tool storage area after use.
6. Precise machining of parts Before the machine starts, it is necessary to check the position of the oil nozzle of the oil pump to prevent the oil from spraying to other locations.
7. Machining clearance If you want to pause the observation, it is necessary to first move the table out of the cutting position
