How It Works: The Data-Driven Manufacturing Chain
Design (CAD): Engineers create a 3D digital model of the part using Computer-Aided Design software.
Programming (CAM): The CAD model is translated into G-code instructions that the machine tool can understand, using Computer-Aided Manufacturing software. This process involves setting critical parameters like tool paths, cutting speeds, and feed rates.
Setup: The operator mounts the workpiece, installs the cutting tools on the machine, and loads or calls up the machining program.
Execution & Monitoring: The CNC system interprets the G-code, precisely controlling the movement of the machine’s axes and auxiliary functions (e.g., coolant, tool changes) to complete the cutting automatically. The operator monitors the process to ensure stability.
Completion: After machining, the part is removed for necessary post-processing (e.g., deburring, surface treatment) and quality inspection.

When selecting materials for CNC machining, a comprehensive trade-off is needed from three dimensions: functionality, machinability, and economy.
From the functionality requirement dimension, it is necessary to evaluate the material’s strength requirements (including static strength and dynamic fatigue strength), wear resistance requirements (often related to surface hardness), corrosion resistance (for specific working environment media), operating temperature range, and electrical properties like conductivity and thermal conductivity.
From the machinability dimension, the material’s machining difficulty level (can be divided into levels 1 to 5), tool cost index, machining efficiency coefficient, achievable surface quality, and difficulty of deformation control need to be considered.
From the economic dimension, calculations should include the cost per kilogram of the material itself, estimated machining labor hours, tool consumption costs, necessary heat treatment or other post-processing costs, and an estimation of potential scrap rates.
When matching materials to application scenarios, the following guidelines can be followed: For aerospace structural components, high specific strength materials like 7075 aluminum alloy are preferred, with titanium alloy TC4 being an excellent alternative, while stainless steel is generally not recommended due to its higher weight. For medical implants, biocompatibility is the primary consideration, making Ti-6Al-4V titanium alloy or cobalt-chromium alloys the first choice, whereas ordinary stainless steel is unsuitable. For lightweight components like optical mounts, 6061 aluminum alloy or brass are ideal choices, while carbon steel is not recommended due to weight issues. For fixtures in high-temperature environments, materials with good thermal stability must be chosen, such as Inconel high-temperature alloys or specialized heat-resistant steels; ordinary steel cannot perform this task.
