Why Jerk, Not Just Speed or Acceleration, Defines a Truly Fast Machine

When aiming for drastically reduced process time in high-performance machinery, focusing solely on high speeds or impressive acceleration rates misses a crucial point. The truly critical factor dictating efficiency in dynamic operations is jerk. Jerk is the rate of change of acceleration—how smoothly and quickly a machine can ramp acceleration up or down. High speed might be theoretically attainable, and high acceleration gets you there faster, but without precise jerk control, significant limitations arise.

When creating a 400 mm long slot, even with a programmed acceleration of 5 m/s² and a target speed of 60 m/min, the machine's actual performance can be bottlenecked by how quickly it manages changes in acceleration.

As the graph below illustrates, jerk is the differentiator. Anker-Tec's machines, with their exceptional jerk capability of 50 m/s³, can accelerate so efficiently that they reach the programmed 60 m/min.

What happens if jerk reduced to 10 m/s³

When jerk, the rate of change of acceleration—for example, reduced to just 10 meters per second cubed (10 m/s³)—it critically impacts machine performance.

At such a low jerk value, there simply isn't enough time or space for the machine to reach its target acceleration, even a modest 5 m/s². Furthermore, the programmed speed of 60 m/min becomes unattainable. The machine will spend too much time attempting to ramp up its acceleration and speed, resulting in it reaching neither its desired acceleration nor its target velocity within the available operational window.

This constraint directly leads to a significantly lower process speed, hindering overall productivity and efficiency.

Carbon Fiber: The Core of Anker-Tec's Uniqueness

This superior capability to manage jerk is made possible by our extensive use of carbon fiber in Anker-Tec machines. Carbon fiber components, with their exceptional stiffness-to-weight ratio, enable rapid and precise acceleration changes without inducing detrimental vibrations or deflections. This advanced material is a key factor that makes Anker-Tec's machinery truly unique in its performance.

Thanks to this, the programmable jerk rates in Anker-Tec machines are significantly higher compared to the competition. This translates into a general process speed that is between two and three times faster than what's achievable with conventional machines, dramatically reducing cycle times and boosting your productivity.
