Can Robot milling replace a traditional CNC machine?

Robot Milling

Robotic milling involves adding the flexibility to replace a traditional CNC machine

Robot milling can now replace a machine tool in certain applications, bringing a high level of flexibility to use different tools in the 3D space. Robots are capable of producing the highest quality complex and unusual geometries parts. For example, robotic milling systems can have flexible tooling for specific material removal.

Robot Milling can process a variety of different materials from alloys to plastics and from foams to timber. A robot is capable of milling any object of any size or shape by just adjusting the robot programming and end-of-arm-tooling.

We can find Industrial robots in a great variety of applications such as handling, welding, assembling and robot milling operations. Especially for machining operations, industrial robots represent a cost-saving and flexible alternative compared to standard machine tools. With the knowledge of interaction along the milling path, a general model-based path correction strategy is presented to significantly improve accuracy in robot milling operations.

Why working with an industrial robot?

Automotive Industry is using Robotics, where the robot usually execute a single routine following a set of 3d-Curves (circular or linear interpolations or PTP (Point to Point) movements). You just need to program the robot once to do the same operation for the whole lifecycle.

milling automation is a fairly new application for robots and not widely used. Programming is still a big challenge because the robot’s programming software does not support automatically programming of multiple tasks and spline-geometry.

With using CAM or robot simulation software, we have the advantage that we can use the CAM-strategy of contour milling, the end mill can follow the splines according to the surface normal.

 Robotic milling is advantageous in several aspects:

  • Increase Flexibility – Robotic milling greatly increases the flexibility of milling.
  • Lower Cost – Robot milling can be cheaper than CNC.
  • Through the flexibility in a workspace, the robot supports undercuts and can work from all directions.
  • A further advantage is the (non-cubic) workspace. In contrary to portal milling machines, a robot does not operate within a fixed frame.
  • Calibration and self-reference of the robot: the robot can reference its own position to the model.
  • Industrial robots can work in diverse areas as 3-D-printing as well as for milling or drafting.

CNC Disadvantages:

  • CNC machines require substantial space in the floor plant.
  • They are very expensive machines and the initial investment is greater than industrial robots
  • No skilful CNC machine operators and it is hard to find them
  • Technology is moving to smart factories instead of manual operations.

Robotic Technology

For a lot of people, numerically controlled CNC machines are what tends to come to mind when they think of automated milling machines. However, it does not mean that this is the only option or that robotic milling is less competitive than the traditional CNC machine. Technology has moved forward at a pace, and robots are now very popular for milling applications particularly when requires a large envelope.

CNC machine supplier intends to sell the idea that the specific, fixed position tasks are the solutions to the manufacturer. In this article, we are not talking about competing between them. CNC machines are very reliable in repetitive tasks once they had been programmed as well as robots are.

The traditional CNC machine very much has it’s place where high tolerances are required or for machining particularly hard materials. Nevertheless, in our role as an integrator, we need to look at the project being planned and guide our customer. Whether it be robotic or a traditional CNC we will recommend the solution most adapted to their needs. As mentioned earlier a milling robotic cell is nearly always a more economical solution where milling large work pieces.

At Phoenix Control, we design, implement, test and install complete robot cell systems. For example, milling cell, welding, palletising, assembly, painting just to mention some. Check also Welding tomorrow

The future of Robotic Automation Systems

Robotic automation systems


The future of robotic automation systems is here with new technologies. It could be the start of a new era of working with robots cooking, robot serving food, robot surgery or what about robot in the construction, lawyers, architecture design?  Who knows what else we will hear about working with robot in the near future!

As well as the many automotive applications, robots are now found in a variety of other industries with this wider use, there has been a significant increase in the number of people or industries that need to work with robots including the process designers, control engineers, architects to mention some of them.

Restaurant’s Robotics Technologies

Manufacturers of new robots are busy launching new products in the past year and, although the take-up still varies between market sectors as automotive, plastic/rubber and food/beverage are the largest users, but new industries are emerging.  Some restaurant has taken a huge step into the future investing in new robotics technologies  Yes, you can finally say that you can be served by a robot!

Medicine is using industrial robots

Scientists in the US have developed an autonomous surgical robot designed specifically to suture – or stitch up – soft tissue. And in testing, this surgical machine – which, it will operate entirely independently of human control. The results, reported in Science Translational Medicine, compare things such as the quality of the suturing, along with the amount of time the surgery took, and the number of mistakes made.

Robot Servicing

Lawyers can get the information with an “artificial-intelligence attorney”. Its capabilities of learning allow it to continue improving its answers and also help keep lawyers up-to-date about new rulings and by reading carefully through every single case it provides quickly the information that might be relevant to the cases. We may probably see them in the courtroom anytime soon.

Robot Integrator

We will find the robotic automation systems not only in robot milling, robotic material handling or robotic welding systems but also in many others unthinkable areas. Phoenix Robotic will keep you updated with the new technologies nowadays simply visit our website and Contact Us.
