GF Machining’s Dynamic Programming Revolution: Bridging G-Code Simplicity and CAM Adaptability for Lights-Out Manufacturing

In the realm of automation, the traditional focus has been on the movement of parts to facilitate machine cutting. However, a paradigm shift is occurring as advanced systems now tackle tasks once deemed too intricate for computer handling. For GF Machining, this evolution takes the form of dynamic programming within its EDM controls, ushering in a new era of automation.

GF Machining has long provided two options for EDM controls: a G-code CNC and a control with an integrated CAM system and human-machine interface (HMI). While the G-code control appeals to users for its simplicity and familiarity, the CAM system introduces dynamic programming, allowing users to fluidly adapt to changes in parameters.

The essence of dynamic programming lies in the control’s ability to autonomously adjust priorities, generating G-code that precisely aligns with the job’s requirements. This feature is a game-changer for operations that demand close operator oversight. Eric Ostini, GF’s Head of Business Development for North America, explains its versatility, stating, “With dynamic programming, you can change it from A-B-C to A-C-B. Or if you need to suddenly prioritize a different workpiece, or if a wire is slightly out of position, you can make those changes immediately.”

Recognizing that some users still prefer the simplicity of G-code controls, especially for straightforward jobs, GF sought to bridge the gap between its G-code and CAM customer bases. The result is the development of the Uniqua control, a hybrid that incorporates both the G-code and CAM systems into a single control.

Uniqua offers users the flexibility to swiftly switch between a G-code CNC and a simplified version of the CAM-integrated control. This innovative approach allows users to benefit from both the simplicity of a G-code CNC and the adaptability of dynamic programming. Eric Ostini sees Uniqua as a strategic move to provide customers with a familiar control while making dynamic programming options more accessible, even to users unfamiliar with its practical application.

Looking beyond immediate applications, GF Machining envisions dynamic programming as a pivotal step toward automating EDM for lights-out manufacturing. One striking example of its utility is the Early/Late capability, where the control autonomously reorganizes programs to maximize work completion without requiring operator intervention. This capability becomes particularly valuable when an operator faces time constraints, such as a Friday afternoon scenario with unfinished workpieces.

Moreover, dynamic programming has the potential to significantly reduce the programming time for EDM programmers planning for lights-out operations. In unattended EDM work, where batching is prevalent, standard controls often necessitate separate programming for each part. However, with dynamic programming, users can efficiently highlight saved jobs, input part positions, and initiate the program, letting the control generate the necessary code automatically.

While dynamic programming doesn’t reach the level of artificial intelligence, it empowers the machine to autonomously generate code, saving valuable operator time. Skilled programmers can leverage this capability to streamline their workflow, focusing on identifying efficiencies rather than engaging in redundant tasks. Eric Ostini sums it up, stating, “Dynamic programming enables the intermediate or beginner operator to function at the level of a skilled programmer and enables the skilled programmer to make more efficient use of their time.”

In essence, the integration of dynamic programming into GF Machining’s EDM controls not only enhances operational efficiency but also positions the company at the forefront of the industry’s shift towards lights-out manufacturing and advanced automation.
