Advanced Cutting Techniques for PET Bottle Threads Using A7075 Aluminum Material

This document details the cutting processes for a sample PET bottle thread measuring 50mm x 50mm x 100mm, utilizing A7075 aluminum. The roughing process involves 3-axis and 3+2-axis machining techniques, followed by semi-finishing with simultaneous 4-axis machining using a 0.5R ball end mill. The integration of a simultaneous 5-axis module enhances the tool path capabilities, allowing for the creation of complex undercut shapes while minimizing setup and programming times. Techniques are elaborated upon with specific machining details for each cutting phase.

  1. 　ＧＲＡＰＨＩＣ ＰＲＯＤＵＣＴＳ ＩＮＣ. http://www.graphicproducts.co.jp Cutting Sample PET bottle threads 50mm x 50mm x 100mm Cutting processes Material: Aluminum (A7075) This sample is threads part of PET bottle. Roughing process was machined with 3 axis machining, Second roughing process was machined with 3+2 axis machining. Semi Finishing process was machined with Simultaneous 4 axis machining for rotating work with 0.5R Ball end mill. Simultaneous 5 axis module converts tool path into simultaneous after generating 3 dimensional tool paths even for an undercut shape. Simultaneous 5 axis module enables to reduce setup time and programming time.
