The "Machining VA/VE Technology Handbook" includes numerous examples of significant cost reductions during the "design phase" that designers should be aware of in machining! In addition to case studies, it is packed with tips for on-site improvements, including key points in machining, mechanisms for cost reduction, and explanations of troubles caused by design issues. It is currently available for free! With simple innovations, you can shorten work hours, skip processes, or avoid the need for special tools. 【Overview of Contents】 ■ Importance of cost reduction in the design phase ■ Correct selection methods for machining processes ■ Explanation of troubles at machining sites caused by design ■ VA/VE cost reduction examples in machining 　□ Lathe machining: 9 examples　　　　　□ Milling: 8 examples 　□ Five-axis and complex machining: 6 examples　□ Electrical discharge machining: 1 example 　□ Measurement processes: 4 examples　　　　　□ Material selection: 2 examples *The downloadable version is a digest.
