An Expert Guide to 5 Axis Machining Software

Are you ready to take your machining to the next level? The right 5-axis machining software can expand your machining capabilities far beyond what you might have previously imagined… but you need the right software tools.

You are probably aware of the benefits of using 5-axis machines over the conventional 3-axis machining tools. With a 5-axis machining process, you can create more complex shapes, improve tolerances, and drastically reduce the need for time-consuming changeovers. Whether you’re using a conventional CNC machine or robot machining, it can be a game changer.

But, it’s not just about extra axes. You programming software can also make an enormous difference to the ease with which you can use this powerful process.

Here’s a brief experts guide to 5-axis machining software:

What is 5-Axis Machining?

5-axis machining is an advanced method of Computer Numerical Control (CNC) machining. The cutting tool moves along 5 different axes independently — and 3 linear axes (X, Y, Z) and two rotational axes around these linear axes (any two of A, B, and C).

By using simultaneous movement over these 5 axes, you reduce the need to manually reorient the workpiece as required in simpler 3-axis machines.

You can achieve 5-axis machining with two primary methods:

1. A conventional CNC machine — With a CNC machine, the 5-axes are fixed based on the configuration of the machine.
2. Robot machining — Performing 5-axis machining with a robot uncovers a whole extra level of flexibility. Find out more in our article Can a Robot Outperform a CNC Machine for Robot Machining?

Whatever method you choose, adding 5-axis machining to your operations can help you achieve higher throughputs, better consistency, and more complex machining operations.

Common Challenges of 5-Axis Machining Programming

Along with its powerful capabilities, 5-axis machining also comes with some challenges, particularly in the more complex programming phase.

A few common challenges include:

• Programming intricate toolpaths can require more advanced programming skills.
• Combining robot programming with CNC path generation for robot machining can require in-depth knowledge of both types of programming.
• The barrier to be entry for 5-axis machining can be high as you need to learn new ways of programming.

Thankfully, there is a way that you can solve these challenges in one step: pick the right programming software.

9 Key Features of Effective 5-Axis Machining Software

How do you find the right software for programming your 5-axis machining task?

Here are 9 key features to look out for in a software program, particularly when you are using robot machining:

1. Collision Avoidance

The complex, dynamic movement of the tools in 5-axis machining can introduce a higher risk of collisions between the tool and the workpiece. Your software should include features to reduce collisions, from basic interaction detection to more advanced AI functionality.

2. Efficient Toolpath Generation

Accurate control of your tool movement is crucial in 5-axis machining. Your machining software should allow you to easily generate and tweak toolpaths.

3. Tool Center Point Calibration

The tool center point (TCP) of your machining tool is the “business end” of the tool. As a result, it needs to be properly calibrated. Your software should have methods to automatically calibrate the tool center point.

See: Automated Tool Calibration for Industrial Robots

4. Toolpath Shortening Algorithms

Efficient 5-axis machining means reducing your tool motions to only the essential movements. Automatic path creation tools (like RoboDK’s PRM motion planner) use AI algorithms to optimize your toolpaths.

5. Toolpath Smoothing

Another feature that can help make your 5-axis machining more efficient is toolpath smoothing. By cutting off rough or unnecessary movements, you can make slight changes that improve your cycle time significantly.

6. Simulation Capabilities

Simulation is key with 5-axis machining, particularly for robot machining. With a simulation tool like RoboDK, you can program and debug your machining application in a virtual environment before putting it into production.

7. Automatic Workpiece Offsetting

A sometimes underestimated feature of machining software is easy workpiece offsetting. This is especially important in robot machining, where moving the workpiece can help avoid robot singularities.

8. Flexibility

Whatever 5-axis machining software you use, it should be flexible to a range of tasks and applications, not limited to specific use cases that might restrict you in the future. This helps you to get the most from the inherent flexibility of both robotic machining and 5-axis CNC machines.

9. Easy Programming

Any software for automated machining should be easy to use, even if you don’t have extensive experience. RoboDK, for example, is designed so that you can easily program robot machining even if you don’t have robotic experience.
