In the transformer equipped with an epoxy resin insulation structure, the formula curve is commonly utilized in the focusing mechanism of optical instruments. As technology advances, the demands for both the accuracy and surface quality of these curves have been increasing steadily. To address these requirements, a novel approach for machining high-precision curves on wire-cutting die components has been proposed. This method aims to enhance both machining accuracy and efficiency while comparing its performance against traditional techniques.
Analyzing the component drawings reveals a product dial part made up of complex curves. These curves consist of three distinct segments, each defined by specific equations:
Ï = 16.5 - 4.1tan(t/2)sin(60° + t/3), for 0° ≤ t ≤ 21.7°
Ï = 16.5 - 4.1tan(1.25t - 16.275)sin(60° + t/3), for 21.7° ≤ t ≤ 30°
23² = (x + 1.2377)² + (y + 10.5667)², for 30° ≤ t ≤ 90°
The dial ring is crafted from Cr12MoV steel, known for its excellent hardenability, hot hardness, and moderate toughness. Each side of the curve must achieve a roughness value of Ra = 1.6μm. Furthermore, after machining, the parts must remain free of defects like deformation or distortion.
Traditional machining methods involve defining a series of discrete points along the curve and inputting their coordinates into a computer for programming. However, reducing the number of discrete points lowers the curve's accuracy, leading to poor surface quality, which fails to meet product standards and impacts overall quality.
To improve upon this, the processing enhancement method employs CAXA Wire Cutting V2’s advanced curve functions for both design and programming, utilizing a Suzhou three-light cutting machine for execution.
Firstly, establishing the curve equation and data file proved challenging due to CAXA’s limited documentation regarding its formula curve editing functionality. Through trial and error, the correct formula input was identified, ensuring consistency between theoretical models and practical outputs.
Next, the graphical representation required entering parameters and equations via the "Formula Curve" menu. Data transfer between different software platforms posed another hurdle since the wire cutting V2 version couldn’t directly utilize the machine tool's programming features, likely due to incomplete software development. To overcome this, an .IGS data interface file format was employed to facilitate seamless communication between V2 and the programming software.
Programming adjustments were also critical; ensuring minimal curve precision settings generated smoother 3B codes with increased point density. Following these procedures ensured compliance with specified technical requirements regarding curve precision and surface roughness.
By adopting this innovative approach, significant improvements in machining accuracy and efficiency were achieved compared to conventional methods. This advancement not only meets current industry standards but also sets a benchmark for future developments in similar applications.
