Programming Without G Code

For manual machinists ready to make the transition to CNC, cutting parts and creating part programs has never been easier. With the new Intuitive Milling System from Haas Automation, Inc., it’s almost effortless. This interactive, conversational software guides the operator through the steps required to machine a part, from establishing tool offsets to drilling bolt circles to engraving serial numbers. An easy-to-read, full-color liquid crystal display (LCD) presents straightforward information for a variety of milling functions.

Knowledge of G-code programming is not required to perform such operations as setting tool and work offsets, drilling and tapping and milling circular or rectangular pockets. The operator simply chooses a function and is then prompted to enter basic machining information such as tool type, work coordinates, depth of cut or drill, speeds and feeds, etc. When all the data has been entered, a push of the Cycle Start button generates the Gcode program and executes the desired operation. The Recorder function can be used to save multiple operations, for future duplication of the part.

From the Tool Setup menu, the operator enters tool type, diameter and number of flutes, as well as workpiece material. Speeds and feeds are then calculated automatically, although they may be modified by the operator. The Soft Stops menu allows limits to be set on machine travels, to limit the risk of a crash – a particularly useful feature when, for example, there is a rotary table within the work envelope. There are also menu tabs for Facing; Drilling; Pocket Milling and Engraving, and the System menu contains the Recorder function as well as information on any alarms that may have been generated, plus a message screen.

The Intuitive Milling System is standard on the Haas TM-2 Toolroom Mill, a versatile vertical machining center that combines the simple functionality of a manual mill with the powerful flexibility of the Haas CNC control. The TM-2 operates in three modes: manual, combined manual/ CNC and full CNC.
