Create CNC broach programs in under a minute with new Program Generator!

   CNC Broach Tool™ LLC has created an online Broach G-Code Program Generator which can reduce your programming time from hours to under a minute. Programming a broaching cycle for your CNC Lathe or Mill is now as easy as entering 8-10 inputs and pressing a button. The web application will export up to 2000 lines of g-code program which the user can then copy and paste into their CNC program.

  Programming a broach tool to cut in a CNC machine can be time consuming. This is because linear broaching in a CNC requires multiple passes which take small amounts of material, usually between .0006″ – .0020”, per pass. A keyway which has a radial depth of .400″ and a depth of cut of .001″ per pass, for example, would require 400 passes. When creating a long hand Lathe or Mill program, each pass requires a minimum of 4 lines of G-code. The general layout for each complete pass is as follows:

  1. Position/Reposition on X,Y, Z
  2. Feed in on Z axis
  3. Retract out on X axis
  4. Retract out on Z axis

  The example above which has 400 passes would require 1600 lines of g-code. Sometimes the length of the program can be condensed by using a sub-program with incremental moves and multiple calls. This generally works unless you have limited clearance behind the tool. For example: Let’s say you have a Ø.750 bore and are using our T6MML tool which fits a Ø.745 min bore. An incremental program with a .150” retract for every pass, will crash after the first pass when it retracts out of the cut on X. In this case, you will need to write a long hand program and set your retract point for each pass to an absolute position of Ø.745 instead of using an incremental position.
