The CNC Keyway broach cut time calculator performs the following:
- Roughly calculates cycle time when keyway broaching in a CNC machine
- App calculates cut time based on keyway depth, length, & depth of cut
- This feature was added by the request of www.cncbroachtools.com
- These calculations may vary depending on the speed of your machine
If you'd like to export the g-code required to broach in your CNC lathe or mill, try the new CNC Machinist Calculator Ultra app which is available on the App Store, Google Play, and on the web. This G-code export is only available in the Ultra version of the app.
Calculate your Clearance Undercut Diameter Below
When broaching a keyway in a CNC machine, you must always program the broach to cut completely through the material and into an open feature such as a cross hole or an internal groove. The most common programming technique is to cut an internal groove (or undercut) behind the keyway. When doing this you must remember that the corners of the broaching insert are farther from center than the flat at the top of the insert. For instance, a tool that is cutting a .375" wide keyway will need an undercut that is .038" larger in diameter than a .250" wide keyway. The calculator below quickly finds the diameter and allows for an additional .025" for chip clearance.
