Except 5 Axis Drill Toolpath CUT CONTROL What does the tool follow? TOOL AXIS CONTROL How is the tool axis controlled? TOOL TIP CONTROL What controls the depth of the tool? Driving multiaxis machines is all about control. 知识回顾Knowledge Review * * * * * * * * * * * * * * * * * IMPELLER ROUGHING STRATEGIES IMPELLER ROUGHING STRATEGIES IMPELLER BLADE SEMI FINISHING FLOOR FINISHING IMPELLER MACHINING HEAD - PORT PORT ALONG COMPLEX Utility – Calculate based on tool center PORT ALONG COMPLEX Headporting MASTERCAM MULTIAXIS OVERVIEW Can result in much better finish and greatly increased accuracy. Can replace the need for multiple set-ups. Can eliminate the need for multiple fixtures and potential set-up errors. Multi-axis toolpaths There are 3 major multiaxis machine types: Table on Table Table - Head Head on Head But there are numerous combinations of these . . .
