What Retrofitting Is & Why You Need It

Fortunately for businesses that invest in CMM equipment, CMM hardware is built to last. Though the initial cost of investment in a new or refurbished machine may be high, the actual structure of the machine is pretty durable, giving decades of use and a great ROI with the right maintenance.

However, in many ways CMM technology is advancing rapidly. Just over the past few years we have seen huge changes in inspection techniques, production methodologies and operator skill sets to name but a few. Plus advancements in software, probing equipment and electronic controllers.

The result is that a typical CMM is unlikely to physically wear out before it simply becomes obsolete. In fact, some types of CMM technology, such as controllers and software, could be obsolescent in as little as three years. It would be madness to purchase a full replacement CMM every few years, so what is the alternative? The answer is retrofitting.

Retrofitting involves selectively replacing and modernising key equipment to improve a CMM’s accuracy and productivity, while leaving the structural components intact.

Why Retrofit?

Businesses choose to retrofit old CMM equipment for various reasons. This may be due to wear and tear, loss of accuracy or simply due to high maintenance costs. Your scales and reader head encoders may have become damaged or your old electronics may not be compatible with newer motors, or your controller may have become obsolete.

A retrofit can be reactive, in response to a mechanical fault, or it can be proactive to increase the capabilities of an older machine.

Candidates for retrofits are often in the final third of their working life cycle, but this is not always the case. Some businesses choose to retrofit fairly new CMM’s in response to changing inspection requirements or new software releases.

A retrofit can completely transform an old CMM to meet the speed, productivity, accuracy and efficiency demands of a modern business – plus many other benefits. A retrofit can add brand-new functionality to increase its versatility and value. In this guide we will look at how this is possible and the way we approach retrofitting at Status Metrology.

Turnkey Retrofitting From Status Metrology

At Status Metrology we offer a turnkey retrofitting solution that includes the latest CMM software, five axis controllers, a wide range of probe sensors and full training. Each retrofit is oriented to the goals of your business and is supported by our ISO 9001 accredited quality systems.

In this section we explain how to plan your retrofits around the life-cycle of your CMM, what is included in a typical retrofit, and the types of hardware and software that can be retrofitted to your old CMM.

How do retrofits fit in with the typical life cycle of a metrology system? While some businesses choose to retrofit a wide spectrum of components in one sitting, this is obviously a costly option. Some systems become obsolete more slowly than others, so it makes financial sense to plan retrofitting as an ongoing practice over several years.

Here is a quick guide to when you might want to replace certain components:

  • Metrology software: we recommend updating software with annually.
  • Computer: Replace after 2 to 3 years.
  • CMM 3-Axis Electronic Controllers: Replace every 8 to 10 years.
  • Hardware, base and mechanical structure: Replace if necessary after 20 years.

What Is Included

Our retrofitting service is flexible, with different levels available depending on the type of machine and your requirements. A typical retrofit may include some or all of the following:

  • New PC and PC peripherals
  • New metrology software, for instance, PC-DMIS or latest versions of an already
  • installed application
  • CMM rewiring to improve electronics
  • Upgrade of CNC control system to incorporate the latest technology
  • New scales and reader heads
  • New probe heads and sensors

Motors, drives and measuring scales are normally left untouched as long as they are in good order and can interface well with the new components. However, sometimes we recommend replacing these components in order for them to work successfully with the new system.

Latest Generation Components

Status Ebuk10

We use the latest generation of CMM products to boost the productivity of your unit, including the following enhancements:

Controllers

Many of the latest controllers are intended specifically for retrofitting. Our own line of controllers are designed to upgrade the capacity of an older CMM to modern standards, giving significant savings compared to the cost of a new machine. Our RC1, B5 and DC family controllers can be retrofitted to practically any brand and type of CMM.

Probe Sensor Changers

Upgrading your CMM to incorporate touch trigger probing with automatic probe sensor changing will hugely increase its measurement abilities.

Automatic Positioning Probe Heads

Status Ebuk9

New automatic positioning probe heads come with a range of increment options to increase the flexibility of your machine. These can be configured at 2.5° angles, 5.0° angles or 7.5° angles.

High Accuracy Scanning Probe Sensor

The latest tactile probes can increase the accuracy of most old CMM models. Options include scanning sensors, tactile probing or continuous contact scanning.

Non-Contact Camera Probe Sensor

Non-contact sensors are one of the most exciting innovations to transform CMM technology over the past decade. Retrofitting can bring this advanced capability to older models of CMM. Upgrade to a non-contact camera sensor: the 2D light-sensitive CCD and integral LED illuminate an area of a measured component and allow it to be viewed in precision accuracy. This allows fast optical measurement for a wide range of large-scale components.

Non-Contact Laser Scanning SensorStatus Ebuk8

Laser scanning sensors provide a range of benefits, including rapid point cloud capture, inspection to CAD (perfect for thin-walled and sheet metal parts), free-form surface inspection and reverse engineering.

Frequently Asked QuestionsStatus Ebuk11

There is plenty to think about when considering a CMM retrofit. In this section we’ve included some of our most frequently asked questions.

Q: What alternatives are there to retrofitting?

You can choose to upgrade an old CMM. Upgrades are proactive responses to changing business requirements and can be customised to improve a desired
characteristic, such as energy, accuracy, speed or throughput. Upgrades are normally more selective in what they replace than a retrofitting service. If your
inspection requirements have expanded drastically, you may also want to consider investing in a new or refurbished machine.

Most businesses approach retrofitting as part of a goal-based improvement plan, which may also include investing in new kit. When we advise customers on the best path to take, we start with your end goal and work backwards from there, recommending the appropriate action to meet your requirements in the most affordable way.

Q: How much does retrofitting cost?

As each retrofitting solution is tailor-made for individual customers, there is no standard cost. Prices are based on the components used, labour and training. All projects are quoted individually and come with full after-sales support and warranty.

Q: Would it be cheaper to retrofit or purchase a new machine?

This depends on the age, size and condition of the CMM you want retrofitting. The cost of a retrofit depends on what components need changing and to what extent the capacity need upgrading. If your machine frame is well serviced and in good condition, a retrofit can easily extend the value and working life of your machine. If this is damaged, however, you may not get the full value from your retrofit. Also, if your old machine has a measuring volume of less than 700 mm, the cost of a more accurate refurbished or new machine may be equivalent to the cost of the retrofit. If your old CMM is in good condition you may be able to part exchange it for a new one, reducing the cost of a new investment. Have a chat with us and we’ll recommend the best course of action for you on a case-by-case basis.

Q: Will my CMM be more accurate or faster after the retrofit?

Retrofitting primarily targets software capability and functionality, which always leads to an improvement in throughput. If your retrofit includes a new controller it can result in smoother cycle times with time savings of up to 30%. However, retrofits don’t directly target accuracy or speed. For this you may wish to consider upgrading the structure of your CMM or increasing your capacity with an additional machine.

Q: What will happen to my part programs after the retrofit?20145815475057132

This depends on the software you use and the compatibility between your old system and the new system. If you upgrade to PC-DMIS, for instance, you will be able to import any compatible DMIS file from your old system, as well as MMIV, Tutor and Master files. However with some new controllers none of your old programs may be compatible, especially if you are currently using old software.

Q: Do you offer servicing for retrofitted machines?

Yes. We offer a complete maintenance and repair service for all types of retrofitted CMM’s, including spare parts, calibration and breakdown cover.

Q: How much training will I need to use the machine?

This depends on how extensively the retrofit changes the CMM’s functions. We provide complete training for your team with each retrofit. These are 3 to 8 day courses held at our regional training centres.
