Examples of Cost Reduction Due to Changes in Design Drawings (Part 1)
The basic idea is "reducing the hassle of tool changes"! Based on this, I will explain the fundamental concept.
The depth of the cut H = end mill diameter φD × 5, with H being ideally within 5D. The higher the depth, the greater the curvature at the tip of the end mill, which affects the dimensions. As a guideline to avoid curvature, if we consider the end mill diameter as φD, the depth of the cut should be kept within 5D to complete the machining in one go. Exceeding 5D will require the cut to be done in two or more passes, which increases the time and consequently reflects on the cost. If it is absolutely necessary to make it smaller than R5 in design, it would be easier to select tools if you specify "R4 or less" instead of just "R4," which can help reduce costs. 【Cost Reduction Points】 ■ Cutting range and height H ■ R size ■ Fillet size *For more details, please refer to the PDF document or feel free to contact us.
