Machine setup is key to minimising chatter I
n the manufacturing of machined parts, vibration is a familiar challenge. Excessive machine vibration - or chatter - and the unwanted shaking of machines leads to increased wear on tools and machines, ultimately resulting in the production of sub- par components which might not adhere to exacting specifications. So, for manufacturers who prioritise efficiency and output quality, finding a way to minimise chatter is essential. Vibration typically corresponds to the
relative movement between the workpiece and the cutting tool, and to overcome it, machine operators will often employ a process of trial and error to adjust machine settings, or fall back on the recommended settings providing by tooling manufacturers. The problem here is that this information fails to take into account particular machine dynamics and setup. As a result, if chatter is still present, machine operators will have to intuitively adjust each of these parameters until a stable operating rate is found. This all takes time - time to work with the machine, to understand the material work holding, and to try different operating parameters of speed, feed and depth of cut. And with each attempt, a trial run is needed, taking more time and resulting in more waste. Even when a suitable operating setup is found, more often than not, it is not the most effective solution. To truly optimise a machine and smartly
reduce chatter, understanding the vibration occurring at the tool tip relative to the material being worked, is essential.
Tooling Technology ThaT reduces chaTTer
Each tool-holder-spindle-machine combination has its own fingerprint - its own set of unique vibration frequencies. Traditionally, understanding these has been time consuming for manufacturers - but it is vital information which supports them in their mission to maximise productivity, control waste and extend tool and machine life. Now, with MSC MillMax - the
milling parameter selection tool - manufacturers can make machine optimisation a much faster

business performance to new heights. At a time when the industry is
undergoing significant change and manufacturers are competing on both domestic and global playing fields, increasing capacity through machine optimisation could be the key to success, enabling manufacturers to grow their business and even tap into new revenue sources.

process. By measuring the specific vibration behaviour at the tool tip, it is possible to gather vital data that manufacturers can use to achieve the optimum setup combination. Using a small sensor attached to the tip of the tool, MillMax gathers vibration frequency data and presents it on a digital dashboard in almost real time. Equipping operators with the vibration frequency data of their unique setups, the MillMax system facilitates the configuration of machine setups which in turn aid the production of parts at the fastest possible speed and influences improved productivity. Taking just minutes to deliver results,
manufacturers can quickly understand their machines and compare multiple setups, without the costly and repetitive trial and error of traditional methods.
reduced chaTTer = improved roi
By reducing the amount of time required to optimise machine set-up, manufacturers will experience reduced cycle times and even get parts to market more quickly and with less waste. But that is just the starting point, with reduced cycle times and quicker optimisation, this will ultimately lead to increased capacity and improved cost competitiveness - driving
