How to Choose a Milling Gear Cutter & Buy One - Milling a Gear 3

We’re showing you how to choose a gear cutter for making gears on a mill. Use the following key parameters: Pitch or Module, Pressure Angle and Tooth Count for the gear you plan to make, then use the involute gear cutter to mill a gear in your ... https://bit.ly/3onfQon own shop. In this video we go through these parameters in detail so you can find an involute cutter for milling a gear.

The devil is in the details. Machineries Definitions D = Working Depth f = Clearance D+f = Depth of Cut But different manufacturers can define clearance differently. Use what is marked on the tool, if not available revert to asking the OEM or using Whole Depth We are rooted in the internationally used standards set by AGMA. For this work we used AGMA ANSI/AGMA 1012-G05 To check your gear when it is done, use the Measurement over Pins (Wires) calculator to make sure you have the pitch circle and tooth thickness you want. https://evolventdesign.com/pages/gear...

A technical joy, plan on rolling up your sleeves. Music: "Loso Solo" Jonathon McEuen His excellent guitar mastery is honed over many years. He wrote this just for the channel along with a few others. I am blessed to have friends with many different talents, and Jonathon definitely knows his craft which gets right to the essence of the channel. Sharing the skill & craft. The history of gears is surprisingly interesting - the process of milling and hobbing gears plus the transmission of torque and movement all find a place here. We will open the "Secret Gear Case" to YT as well through this channel - a personal mission. https://evolventdesign.com​ To learn about lubricants for your machines https://oilviscositychart.com​   / villagehobber   Disclaimer: https://evolventdesign.com/policies/t...
