Touch probe manufacturer use coordinate measuring machines (CMMs) for dimensional measurement with contact probes. Concorde engines, one of the Rolls-Royce Olympus engines fitted on the aircraft, were the first to use the contact probe in solving dimensional quality inspection problems.
Probing a component provides accurate, repeatable geometric data because it is essentially an elaborate switch. In addition to ensuring components remain within the tolerances throughout the manufacturing process, this data can also interrogate to monitor how well it is working.
Manufacturers seek to improve dimensional accuracy while reducing setup times and minimising machine downtime; touch probes offer several advantages. Many touch probes that are available today can integrate into machine tools and CNC controls, particularly milling machines and other multi-axis machining centres.
How Touch Probes Work For Touch Probe Manufacturer
The probes are known as touch-trigger probes. They gather multiple data points by touching a workpiece or tool-allowing better to measure the workpiece’s position and machining settings accordingly.
The tool changer or the user inserts the touch probe manually into the tool holder. NC controls configure to perform the following functions automatically or manually, depending on their probing functions.
Specific applications for touch probes
The following are some of the most common applications of touch probes in the workpiece or tool monitoring/positioning for touch probe manufacturers:
In particular, it is helpful to align workpieces parallel to the axes when their existing reference surfaces are already partially machined, allowing them to define their position accurately. This process accelerates touch probes; once the workpiece is clamped, the probe will analyse its position and discover any misalignment. Touch probes convey data back to the control system, compensating for the misalignment by rotating the rotary table or re-calibrating the coordinate system.
Set the presets
Presets reference in programs for machining workpieces. Workpiece touch probes reduce nonproductive time by finding this point quickly and accurately. Using a touch probe can automate preset settings according to your CNC’s probing features.
A touch probe determines the position of a piece of material between two steps of machining, for instance. The measurements can be used to account for wear on the tool. As the workpiece is complete, the measured values can monitor machine trends or document dimensions accuracy. Measurement results can be output through the data interface of the CNC. Thus, machining errors can be detected and corrected immediately without reclamation.
Measurement and cyclical inspection of tool wear are essential factors in achieving high machining accuracy. Tools are measured correctly on the machine via a touch probe–even down to individual teeth on milling cutters. CNCs store measurement data in a tool memory to be used later in part programs. Additionally, you can use a cuboid probe to measure lathe tools and ensure they are not broken or worn out.
Calibrating rotary axes
With the development of 5-axis machining, accuracy requirements have become more stringent. For complex parts to be manufactured accurately and reliably over time, they need precision and reproducibility. In some cases, touch probes and compatible machines can minimise measurement error in a machine’s kinematic description by calibrating the rotary axes. The ability allows for sustained high-accuracy machining from single parts to large production runs.
