Tagalog The CNC system of a CNC rolling and bending machine matches machining parameters based on material characteristics, mainly based on the hardness, toughness, thermal expansion coefficient and other characteristics of the material, as well as cutting performance, tool life and other factors. The following are the key steps for CNC systems to match parameters based on material properties:
1. * * Material characteristic analysis * *:
-The CNC system first identifies the type of material, such as metal, plastic, or ceramic.
-Based on the different characteristics of materials, systematically evaluate their effects on cutting force, cutting temperature, tool wear, etc.
-For metal materials, the system considers their hardness and toughness, selects appropriate cutting speed and feed rate, and ensures cutting effectiveness and tool life.
-For plastic materials, the system focuses on the heat generated during cutting to avoid material deformation or melting caused by overheating.
-For ceramic materials, the system pays special attention to their hardness and brittleness, selecting appropriate cutting speeds and tool materials to prevent damage during the cutting process.
2. * * Cutting parameter selection * *:
-Cutting speed: Based on the hardness and cutting performance of the material, the system selects the appropriate cutting speed. For harder materials, the cutting speed is usually lower to reduce cutting pressure and heat accumulation; For softer materials, the cutting speed can be appropriately increased to improve machining efficiency.
-Feed rate: The feed rate determines the speed of the workpiece in the machining direction. The system adjusts the feed rate based on the cutting performance and processing requirements of the material, ensuring the stability and efficiency of the cutting process.
-Cutting depth: The system sets an appropriate cutting depth based on the thickness and hardness of the material, avoiding cutting that is too deep or too shallow, in order to reduce tool wear and improve machining quality.
3. * * Tool selection and matching * *:
-According to the cutting performance and processing requirements of the material, the CNC system selects the appropriate tool material and type. The selection of cutting tools has a significant impact on cutting effectiveness and machining efficiency.
-The system will also consider the lifespan and replacement cycle of the cutting tools to optimize their use during the machining process.
4. Real time adjustment and optimization:
-During the machining process, the CNC system obtains real-time machining data, such as cutting force, cutting temperature, etc., through sensors and monitoring devices.
-Based on real-time data, the system fine tunes the processing parameters to adapt to changes in material properties or unstable processing conditions.
-This real-time adjustment and optimization can ensure the stability and efficiency of the machining process, improve machining quality and efficiency.
In summary, the CNC system of the CNC rolling and bending machine has achieved the goal of matching machining parameters based on material characteristics by deeply analyzing material characteristics, selecting appropriate cutting parameters and tools, and adjusting and optimizing the machining process in real time, thereby improving machining efficiency and quality.
