What is a CNC Robot Arm?

Industrial Robot Arms Applications in Plastic Manufacturing

A Computer Numerical Control (CNC) machine is a stationary machine that is configured using coded programming to perform particular production processes. Most of the processes a CNC machine executes, such as plasma cutting, are often dangerous for human employees. CNC robot arms are designed to solve this dilemma.

A CNC robot arm is programmed to work in conjunction with a CNC machine. It follows prompts and executes a series of tasks that complement the working of the CNC machine.

Functions of a CNC Robot Arm

Material Removal

After the production process in the CNC machine, products may have defects such as loose material or rough edges. A CNC robot arm can be programmed to correct such problems before transferring the product to the next stage of production.

Welding

Welding involves high heat, blinding sparks, and harmful fumes. It also requires the positioning of the object being welded to be accurate and consistent. Using a CNC welding robot arm increases the rate of production of welded products, delivers quality work, and protects workers.

Machine Tending 

CNC machines are preferred due to their accuracy and speed. Plasma cutting, for example, happens at light speed with inimitable attention to detail. However, it is a procedure characterized by high-heat and flying sparks. It is, therefore, safer to use a CNC machine tending robot arm as it would not be damaged or slowed down by any of the risks.

Similarly, drilling requires accuracy not just from the machine but also in terms of the positioning of the object. For a human operator, there is a risk of getting injured by the drill and the immense amount of noise it produces can be deafening. All these factors considered, using a CNC robotic arm would deliver better results and a healthier work experience for staff.

Multitasking

Operating a CNC machine involves tending to the machine and the products it puts out as well. A CNC robot arm is fast and nimble enough to multitask in a sequence without getting exhausted or requiring breaks. It reduces the need for many workers on the factory floor and saves on labor costs.

Increasing the Scale of Production

Relying on labor is limited to a prescribed number of working hours for staff. There is also only a considerable amount of work that workers can do within those hours. Both these factors limit the scale of production whereas incorporating CNC robot arms could elevate the scale of production significantly.

Payload

The payload determines the weight of objects that the CNC robot arm can handle. Payloads can vary from 1Kg to 1000Kg. The right amount all depends on the kind of loads the robot arm will be tasked with.

Degrees of Freedom

The more degrees of freedom it has, the more a CNC robot arm can achieve. 6-axis CNC robot arms are highly popular for their dexterity. However, 7-axis designs that can perform even more complex maneuvers are gaining traction.

Position Repeatability

Working in relation to a CNC machine is a repetitive process. The ability to maintain a repetitive consistency of about +/- 0.5mm is vital to avoid situations where the CNC robot arm veers off course.

Reach

Loading raw materials, unloading products, packaging, and other tasks require a CNC robot arm to have adequate reach. The ideal reach distance should be enough to access objects but not too much that it does not fit in the work area.

Flexibility and Rigidity

Flexibility enables the CNC robot arm to stretch and fold to reach objects with ease. Rigidity helps to keep the motions of the arm within the prescribed work area. A balance of these 2 features plays a key role in the precision of the robot arm during tasks.

Multitasking Capabilities

A CNC robot arm is not limited to one skillset. On the contrary, with the right programming, it can be highly adaptive and execute a myriad of roles.

Safety

A CNC robot arm does the hazardous jobs that staff would otherwise have to strain or risk their lives to get done.

Flexibility

A CNC machine is beneficial in many aspects but it is severely limited by its rigidity. On the other hand, the flexibility of a CNC robot arm makes it easy to operate and dexterous enough to perform a multitude of tasks.

Accuracy

CNC Robot arms are fitted with reducers that provide some level of rigidity to facilitate measured movements. This makes them accurate in executing their functions and safe to work around as their operations are targeted and not haphazard.

Speed

Carrying heavy loads or handling risky materials slows workers down. Fortunately, a CNC robot arm is not overwhelmed by such challenges. It works fast and maintains a regular rate of repeatability thereby shortening production times.

Cost-effectiveness

One CNC robot can take on the responsibilities of multiple workers and greatly reduce labor costs. Further, by reducing production times it eliminates the need for overtime pay and high energy costs from long hours of machine use.

Loading and Unloading 

Milling and drilling are some of the production processes performed by a CNC machine. They involve loading the machine with heavy raw materials and eventually collecting the finished product. A CNC machine tending robotic arm is designed to effortlessly see to all these processes. It handles loading and unloading during production by:

  • Picking and placing raw material in the CNC machine
  • Prompting the door to close for the machine to begin processing
  • Collecting the finished product
  • Packaging the product or transferring it to the next production step

Changing Tools

A CNC machine uses different types of tools such as drills, saws, pistons, among many others, during production. Changing them manually takes time as it would involve an engineer unscrewing them in a very small workspace. Most workers may also not have the skills to handle such tool changes as they are quite technical.

In comparison, a CNC machine tending robot arm with an end-effector will only take a few minutes to complete a tool change. It can manipulate its way into the CNC machine’s chamber and has enough power to easily uninstall and replace parts.

Cleaning Workspaces

Welding, die-casting, plasma cutting, and similar processes at an industrial level can be quite messy. They lead to the production of dust, soot, and other by-products. Due to this, a CNC machine unit and the adjacent factory floor space require regular cleaning.

A machine tending robot arm is well-suited to clean factory machinery as it can access hard-to-reach areas. Additionally, it can be fitted with a suction mechanism to vacuum out the dirt which is a safer way to clean machines. Using a robotic arm also protects workers from inhaling harmful chemical residues during cleaning.
