So, the robotic plasma cutters are:

  • Heavier and less portable
  • Automated operation
  • More costly
  • More precise and accurate

Are CNC plasma cutters & Robotic Plasma cutters the same?

No, they are not the same. A CNC Plasma Cutter is a computercontrolled cutting machine that uses a plasma torch to cut through metal and other materials. A Robotic Plasma Cutter is a machine that has been automated with a robotic arm to control the cutting process. The robotic arm allows for greater accuracy and speed when cutting.

Handheld Plasma Vs CNC Plasma

A CNC (Computer Numerical Control) plasma cutter is a machine that utilizes a plasma torch to cut metal with precision. It is computercontrolled and uses a software program to guide the plasma torch along a desired cutting path. The CNC plasma cutter is a stationary machine, meaning it is not able to be moved around a facility or job site. It is typically used in large production lines or fabrication shops requiring high-precision cuts.

A robotic plasma cutter is similar to a CNC plasma cutter, but it is mounted on a robotic arm. This arm can be programmed to move the plasma torch in any direction and position, allowing the cutting torch to be used in various locations and applications. The robotic plasma cutter is mobile, meaning it can be taken to a job site in order to make onsite cuts. It does not require the same level of precision as a CNC plasma cutter, but it is more flexible and can access hardtoreach areas.

So, a CNC plasma cutter is stationary and used for high-precision cuts, while a robotic plasma cutter is mobile and used for more flexible cutting applications.

Challenges of Robotic Plasma Cutter Implementation

Below are the major challenges if any organization wishes to implement this technology for flexible metal cutting.

Cost: Robotic plasma cutting is one of the most expensive methods of cutting available. It requires a significant investment in both the hardware and software and often requires specific training for the operator. This can be a challenge for many companies that are just beginning to explore automated cutting solutions.

Accuracy: The precision of robotic plasma cutting depends on the quality of the hardware and software used, as well as the operators skill and experience. If the equipment or software is not up to par, then the cut pieces may not meet the desired precision, leading to wasted material, time, and money.

Flexibility: Robotic plasma cutting is best suited for repetitive tasks, such as production runs. It can be difficult to quickly adjust the robots settings to accommodate different shapes and sizes, or to make changes midrun.

Maintenance: Robotic plasma cutting systems require regular maintenance and calibration, which can be costly and timeconsuming.

A case study from the University of Maine provides a good example of the implementation challenges of robotic plasma cutting. The university was using a plasma-cutting robot to produce parts for wind turbines. The robot was not cutting accurately, and the university found that the operator had not been properly trained on the software and was not performing regular maintenance on the system. After several months of retraining the operator and troubleshooting the system, the university was able to improve the accuracy of the cuts and reduce the amount of waste material.

Approximate cost
