Integrating dimensional control on the shop floor requires addressing temperature, vibration and shift-operation issues. The iSF, developed by LK Metrology, is a bridge CMM designed for production: it operates without compressed air, tolerates thermal variations up to 30 °C and uses linear motors that eliminate preventive maintenance.
Context and challenge
Most three-dimensional measuring machines require climate-controlled rooms and pneumatic infrastructure. That limitation keeps control away from the assembly line, increases response times and reduces inspection frequency. Small manufacturers face high costs to prepare the environment; large factories multiply investments if they intend to install metrology in every production cell.
LK Metrology designed the iSF to overcome these obstacles. The machine incorporates independent X and Y axes, which allow active compensation of thermal drift, and a pneumatic damping system on a granite base that isolates vibration. The absence of compressed air simplifies installation and reduces operating costs.
The solution or technology
The iSF features a bridge architecture with full front table extraction, providing three-sided access. The linear motors eliminate brushes and mechanical transmission systems, removing wear and lubrication intervals. The TouchDMIS software integrates a glove-usable touch screen, barcode reading for fast program changes and a camera for remote support.
Thermal compensation covers both machine and part, ensuring repeatability even with temperature swings between 15 and 30 °C. The automatic probe cleaner, anti-granular system and robot compatibility (digital inputs/outputs and Modbus) reinforce its industrial vocation. LK Metrology offers original-accuracy warranty for ten years.
Industrial applications
The machine performs dimensional measurements of distances, diameters and radii, control of geometric tolerances — flatness, cylindricity —, verification of relative positioning — coaxiality, perpendicularity — and CAD comparison via 3D color maps. Automatic programming for parametric production speeds up the start of new batches. Connectivity with robots enables closed-loop inspection without manual intervention.
Results and benefits
Eliminating the compressed-air requirement reduces installation and energy costs. Operation between 15 and 30 °C removes the need for dedicated air conditioning, bringing metrology closer to production. Linear motors eliminate periodic maintenance and increase availability. Active thermal compensation ensures reliable data even in variable environments. The touch screen and program change by barcode accelerate part turnover and reduce setup errors.
