G73 Cycle Introduction. In CNC Machining Centers (CNC Milling machines) G73 command (G73 cycle) is used for drilling holes that are deep and that cannot be drilled in one time or that may result in tool breakage, chip jamming. With this cycle, the tool move to the coordinate specified in the program, rapidly approaches the height of Z specified ...

Drilling produces a round hole in a workpiece. A tapping or drill press machine performs drilling operations. However, drilling can also be handled with a milling machine. When machining a workpiece, chips are the waste material produced during the machining process. The way the drill bit is shaped enables chips to fall away from the workpiece.

Firstly, the end mill moves along a helical path. It means that the milling center must combine the vertical z-axis movement and the horizontal x-y axis. This makes the NC program very complex to write manually, however, a lot of CAM-systems have adopted helical milling as one of the strategies. The geometry of the chip consists of two zones ...

The modern 5-axis vertical mills offer possibilities to rotate the part for more access and faster turnaround times. Automating all the movements results in better accuracy, quicker lead times and close to identical batches of parts. The advantages of vertical milling: Considerably cheaper than horizontal mills, with a price difference up to 4-5x

In 1861, Brown & Sharpe created the groundbreaking Universal Milling Machine, which could mill complex part geometries with movement in three axes. From there, production took off as WWI approached. Milling technology developed rapidly for the next few decades, and the introduction of high-accuracy machines like the Jig Bore set the standard for milling …

The milling machine is the workhorse of the machine shop. In essence, a vertical mill is like a drill press except it is fitted with sturdy bearings capable of handling side as well as end loads. Normally up to 85% of machining jobs will require a mill rather than a lathe. Unlike a lathe that spins the material, a mill holds the material firmly ...
