Description: CNC tabbing strategy with pre-drilled holes! In softer materials, plunging isn't a problem but when milling harder materials like D2 steel, there's a strong case for pre-drilling holes before tabbing the workpiece. Not only does this reduce tool deflection, it also preserves tool life by keeping a constant chip load, and there's one more benefit--better chip evacuation! Let's set up tabs in Fusion 360 and compare tabbing with and without pre-drilled holes using common endmills! 00:00 - Intro: Knifemaker Struggles with Tool Life 00:55 - Creating Tabs in Fusion 360 01:27 - Slotting 1018 Steel 01:52 - Titanium 6AL-4V without Coolant: NOT GOOD. 02:12 - Pre-Drilling D2 Tool + Coolant 03:16 - Slotting Before Tabs + Tooling 04:02 - Tabbing: Chip Color & Increasing Plunge Rate 04:54 - Tabbing without Pre-Drilling 05:28 - Results: Tool Deflection, Chips Holding Heat 06:03 - Using This Strategy for Desktop CNC Machines 06:45 - Outro: Grimsmo Makes Knives... 5 Reasons to Use a Fixture Plate on Your CNC Machine: bit.ly/3sNA4uH ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reach us / CNC Info: Speeds & Feeds: provencut.com Download Fusion 360: dpbolvw.net/click-9255839-12529306 Online Fusion 360 Training: bit.ly/LearnFusion360 SMW Products: saundersmachineworks.com CNC Resources: nyccnc.com
