How to Use Robots to Improve Efficiency"},"content":{"rendered":"\n

High-efficiency machining can mean different things to different manufacturers, including maximizing material removal rate, reducing computing load, and improving process workflow. Robots are a popular route to achieving higher efficiencies, but there are some important strategies to remember to get the most from them.<\/p>\n\n\n\n\n\n\n\n

Although the term efficiency means a few different things, robots can be a highly effective way to improve almost all types of efficiency when used correctly. However, the lower structural stiffness of robots means that high-efficiency milling needs special attention.<\/p>\n\n\n\n

With the right strategies (e.g. posture planning, chatter suppression) and the right CAM software, you can achieve high-efficiency milling with industrial robots.<\/p>\n\n\n\n

In this guide, we look at what it means to have high efficiency in machining and how you can use robots to achieve it.<\/p>\n\n\n\n

What “Efficiency” Actually Means in Machining \u2014 and Why It Matters<\/h2>\n\n\n\n

The word efficiency is used in at least four different ways in manufacturing. Before you try to create a high-efficiency robotic milling cell, it is useful to consider what type of efficiency you are actually trying to improve.<\/p>\n\n\n\n

Here is a brief comparison of what efficiency means in manufacturing:<\/p>\n\n\n\n

Machine efficiency (OEE)<\/strong><\/td>Availability \u00d7 Performance \u00d7 Quality<\/td>Production floor management, maintenance<\/td><\/tr>

Let’s look at these in a little more detail:<\/p>\n\n\n\n

1. Machine Efficiency (OEE)<\/h3>\n\n\n\n

Overall Equipment Effectiveness (OEE)<\/a> is an extremely common metric in manufacturing. It’s an industry standard for measuring the productivity of any particular machine.<\/p>\n\n\n\n

An OEE of 100% would mean that your manufacturing process only produces good parts as fast as possible, with no downtime and at the required quality standard. Machines with a world-class OEE<\/a> benchmark at around 85%.<\/p>\n\n\n\n

2. Process Efficiency<\/h3>\n\n\n\n

For most manufacturers, high-efficiency machining means process efficiency. This is a measure of how much material a machining process removes, how fast, and at what surface quality.<\/p>\n\n\n\n

In robotic machining, process efficiency presents both the greatest potential and the greatest challenges for many setups.<\/p>\n\n\n\n

3. Computing Efficiency<\/h3>\n\n\n\n

Computing efficiency is a metric that shows up in some robotics research,<\/a>. It describes how little processor load a control algorithm requires to run.<\/p>\n\n\n\n

As a manufacturer, computing efficiency is probably less important to you than process or machine efficiency in terms of improving your production output.<\/p>\n\n\n\n

4. Robotic Efficiency<\/h3>\n\n\n\n

The term efficiency is often used to market robotic systems. Unlike more specific robotic terms like repeatability or payload, the efficiency of a robot has no standard definition.<\/p>\n\n\n\n

If you see a particular robotic system marketed as being high-efficiency, it’s worth doing a little digging to find out what the manufacturer actually means by this.<\/p>\n\n\n\n

Why Robots Are a Reliable Route to High-Efficiency Machining<\/h2>\n\n\n\n

Robots offer several structural advantages that can contribute to both machine efficiency and process efficiency.<\/p>\n\n\n\n
