When Australia-based machine shop, Hammond Engineering, found that manually setting workpiece positions was time consuming and difficult to repeat, it looked to the potential of on-machine probing.
Since using Renishaw’s OMP40-2 optical transmission probe, the company has experienced faster set-up times and higher levels of productivity.
Hammond Engineering is a machine shop based in Bairnsdale, Victoria. Its services include computer aided design, CNC milling and turning for production sizes ranging from prototyping to large industrial runs.
“I started Hammond Engineering to combine my passion for metalwork with my love of IT,” explains Travis Hammond, founder of Hammond Engineering. “After completing my First Class Machinist apprenticeship, I found a second hand CNC lathe and went from there. Now, we’re a team of three working to provide a more technology focused engineering service than the area has had in the past.”
The company primarily works with customers in the food and aftermarket automotive parts sectors, but also offers general manufacturing and repairs for local industrial businesses.
“When doing general job shop type work, our team must change machine set ups several times during the day,” Mr Hammond continues. “Time taken to make changes, for example to align a vice or set up a workpiece, means time that the machine is not running. In such a small business, lost time is costly, so we started looking for a way to increase productivity, reduce turnaround times and reduce human error.”
“As we are a very small business looking to reduce costs, we often buy machines second hand,” he explains. “When we purchased our latest machining centre, it came with a Renishaw probe attached, so we began to use it for part set-up to see if we could improve accuracy and productivity.”
Hammond’s machining centre was fitted with an OMP40-2 probe from Renishaw. This ultra-compact 3D touch-trigger probe with optical signal transmission is primarily used for workpiece set-up and inspection in machining centres. It offers users up to a 90% reduction in set-up time, as well as a reduction in scrap and fixture costs.
Since using the OMP40-2, Hammond Engineering has experienced faster set-up times. For example, before using the equipment, aligning a vice would typically take around five minutes to complete. With the OMP40-2 this task takes less than a minute. The benefits will add up over time – if the team uses the probe to help align one vice a day, the company will save 17 hours a year. Using the probe also reduces the chances of human error impacting production because it can calculate angles without the need for human intervention.
“I can’t believe it took me this long to realise how valuable probing is in my work environment,” Mr Hammond concludes. “Now that I can see how user-friendly and accurate the OMP40-2 is, it would be hard to convince me to use anything else.”
In the future, Hammond Engineering plans to use the OMP40-2 for in-process measurement on repeat parts to ensure correct positioning and alignment. The company also plans to use tool breakage detection to improve process reliability and confidence.
