Design Difficulty Analysis

Complex features such as deep cavities, undercuts, thin walls and curved surfaces require careful verification of tool accessibility, cutter interference and clamping space. Designs with poor manufacturability will lead to increased cost, prolonged lead time or even unprocessable structures.

High-precision parts require strict control of dimensional tolerances, form tolerances and position tolerances (such as concentricity, perpendicularity, flatness). Cutting force deformation, machining thermal deformation and clamping errors all affect final accuracy, requiring comprehensive process compensation.

Different workpiece materials vary greatly in cutting performance. Hardened steel, titanium alloy, superalloy and other difficult-to-machine materials cause rapid tool wear, poor surface quality and easy workpiece deformation, requiring specialized tools, cutting parameters and cooling solutions.

Complex parts usually require multiple processes, multiple setups and even multiple machine tools. Process route design needs to reasonably arrange the sequence of roughing, finishing and heat treatment, and control cumulative errors from multiple clamping, which highly relies on process engineering experience.

Thin-walled structures, slender shafts and low-rigidity workpieces are prone to elastic deformation under cutting force, resulting in dimensional deviation, vibration chatter and poor surface quality. Design and process need to be optimized simultaneously to ensure structural rigidity and machining stability.

5-axis and multi-tasking machining involves complex tool path programming and motion simulation. Engineers must verify collision risks among the spindle, tool holder, workpiece, fixture and machine tool body, which requires professional programming skills and simulation software support.
