Four common methods for CNC lathe manufacturers to optimize machining processes and programming
The processing of CNC lathes cannot be separated from the support of programming. A perfect programming method is not just a job for the machine, but also a pleasure. Removing unnecessary redundant codes has a significant impact on both processing efficiency and extending equipment life. Therefore, a good machine must be equipped with perfect processing technology and programming methods.
Today, as a CNC lathe manufacturer, we will explain four common methods for optimizing processing technology and programming.
1. Reasonable cutting parameters:
Finishing parameters: During finishing, a smaller cutting depth, a smaller feed rate, and a higher cutting speed (within the allowable range of the machine tool and cutting tool) are employed. A smaller feed rate can significantly improve surface roughness, while a smaller cutting depth can reduce deformation caused by cutting forces.
Avoid overcutting/undercutting: Ensure that the parameter settings effectively remove material and avoid insufficient or excessive actual cutting depth caused by tool letting or vibration.
2. Scientific cutting path:
Constant linear speed cutting: For turning end faces or contours with significant diameter variations, use the G96 constant linear speed function to ensure a constant cutting speed at the cutting edge, achieving more consistent surface quality and dimensional accuracy.
Uniformization of finishing allowance: After rough machining, a uniform and appropriate finishing allowance (typically 0.1-0.5mm, depending on the workpiece and accuracy requirements) should be left. Uneven allowance can lead to fluctuations in cutting force during finishing, affecting accuracy and surface quality.
Smooth and continuous path: When programming, avoid sharp changes in path direction, and use circular arc transitions instead of sharp corner transitions to reduce the impact and vibration of machine acceleration and deceleration.
Layered cutting: For deep grooves and areas with large allowances, layered cutting is employed to avoid tool overload and tool deflection.
3. Reduce/eliminate deformation caused by cutting force:
For thin-walled/weakly rigid workpieces: Optimize the clamping method (such as adding supports, using axial clamping instead of radial clamping), and adopt methods such as small cutting depth, multiple passes, and symmetrical machining to balance the cutting force. Consider using a follower or center rest.
Tool rigidity: Select a tool holder with good rigidity or a thicker tool holder.
4. Rationally utilize compensation functions:
Tool nose radius compensation: Properly use G41/G42 tool nose radius compensation during programming to avoid overcutting or undercutting caused by tool nose radius.
Tool wear compensation: During the machining process, regularly measure key dimensions, and input the deviation between the measured value and the theoretical value into the system as the tool wear compensation value (usually modifying the X/Z or R/T values in the tool compensation code).
The above are the four commonly used methods for optimizing machining processes and programming, which we, as CNC lathe manufacturers, have compiled and released for everyone. We hope the explanations above will be of some help to everyone when using CNC lathes in the future.
