Break Up Long Chips with FANUC Servo Learning Oscillation Function

ETASIS produces custom machine tools for many applications, including high-technology end-users like automotive and aerospace. Long, coiled chips can cause many problems such as conveyor stoppages, substandard surface finishes, and reduced tool life.

Meliha Günaltin, General Manager at ETASIS, explains: "The FANUC Servo Learning Oscillation function increases the production quality of the machines we produce. In materials and processes with a high probability of chip wrapping, the chip formed cannot be removed and causes quality loss with time when the part is processed with traditional methods."

"In mass production areas, the chip formed needs to be cleaned off the part, for continuing the next processes smoothly. This causes additional labour requirement and costs. In addition, a chip-free workpiece is inevitable for customers who want to implement a robotic automation system such as machine loading and unloading. In various tests with the FANUC Servo Learning Oscillation application, we eliminated the chip off the part."

Ms. Günaltin goes on to explain how they utilise the function:

"After the suitable cutting conditions of the workpiece are determined, the specified conditions are entered into the setting instructions of the Servo Learning Oscillation application and the function is ensured to run smoothly. We carried out R&D studies to determine the optimum values for the chip-breaking function.

We also use it for drilling and milling machines along with lathes. The FANUC Servo Learning Oscillation application eliminates the need for chip breaker equipment and for additional labor. It provides us with high benefits in terms of cost and time. In addition, this function extends the tool life, providing a significant cost reduction and efficiency in production."
