Canadian CNC machine manufacturer AXYZ have a neat blog with weekly tips. A recent one addresses the differences – simple as they may be, they still elude many – between downcut and upcut router bits:
Tool selection is critical when it comes to achieving a desired surface finish, tool life, or cut speed of a specific material. Tooling manufacturers go to great lengths to engineer tools to deal with specific aspects and properties of certain materials. Selecting the right tool for the job could determine whether a job fails or succeeds.
In this scenario, we are discussing the different between upcut and downcut CNC router bits.
The actual tips are short & to the point so read them here.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
