COORDINATE MEASURING MACHINE PROBING SYSTEMS

COORD3 Coordinate Measuring Machines can be equipped with tactile CMM sensor technology from Renishaw. CMM Machines can be supplied with touch-trigger probes or analogue scanning probes.

Renishaw is world renowned global supplier of CMM probing systems. For almost 40 years Renishaw has developed CMM probing technology and has subsidiaries to support its products around the world. Renishaw has pioneered touch-trigger and scanning sensors along with it PH10 range of motorised probe heads; its products offer unmatched reliability and low cost of ownership complimented by its unique ‘repair by exchange’ (RBE) program and its 3 years warranty extension program.

Coord3 has partnered with Renishaw as its probing supplier; this unique partnership provide free probe changers to COORD3 CMM customers under the ‘Free Changers’ program when acquiring a PH10 or PH20 equipped CMM.

Touch-trigger probes measure discrete points, making them ideal for inspection of 3-dimensional geometric parts. Renishaw provides a comprehensive range of systems to meet the application needs and budget constraints of all CMM users, from simple CMM feature checks on manually to complex geometry part measurements.

Scanning probes are miniature measuring machines that can acquire several hundred surface points each second, enabling measurement of form as well as size and position. Scanning probes can also be used to acquire discrete points in a similar way to touch-trigger probes.

Indexing probe heads are designed to position the probe at an angle to the part under inspection so measurement can be carried out at suitable probe angles. The repeatability of the CMM index head allows the recall those positions without the need for probe requalification, saving operator time and applying the probe to the surface at the best angle for the most accurate result. Probe Head can be manual or fully automatic.

5 Axis probe systems In conventional CMM measurement methods the CMM structure performs all of the movements necessary to acquire the surface data. CMM structure accelerations induces inertial deflections into the machine frame, which in turn induce measurement errors. CMM manufacturers have devoted years to develop techniques that reduce these dynamic errors, but there is an upper speed limit imposed by the machine and servo system stiffness, beyond which measurement cannot be taken with reliability.

Renscan5 breaks through that limit by using an articulating head that moves in two rotary axes as it measures. This allows the CMM to do what it is best designed to do – move at constant velocity in a single vector while measuring. As the head is much lighter and more dynamic than the CMM, with a significantly better bandwidth, it is able to quickly follow changes in the part geometry without introducing harmful dynamic errors, which results in much faster surface speeds and hence shorter measurement cycles. 5-axis scanning technology allows the user to achieve unprecedented levels of throughput whilst maintaining current levels of metrology.
