Probe Measurement
Vision measuring machines can cooperate with the UK Renishaw high precision touch probe for the measurement as below:
1. Height measurement: use probe to touch a standard plane and many other measuring planes, program will automatically get the height difference between measuring planes and the standard plane.
2. Plane measurement: touch at least three points in the measuring plane, right mouse click to finish, then you can get this plane's inclination and flatness.
3. Sphere measurement: use probe to evenly touch three points on the bigger diameter part of measuring sphere, then touch the top of the measuring
4. Cylinder measurement: touch three points around the cylinder at the same height, then touch another three points at another height, finally you can get the cylinder's radius and inclination.
5. Cone measurement: touch three points around the cone at the same height, then touch another three points at another height, finally you can get this cone's radius and inclination.
6. Circle measurement: use probe to evenly touch at least three points on the measuring object, right mouse click to finish, then you can measure an inner circle.
Usage Scenarios
Precision Milling of Large Aircraft Components
An aerospace manufacturer uses this optical linear encoder to achieve micron-level accuracy when milling massive aluminum structural components for commercial airliners. The long measurement range of up to 3000mm enables precise positioning across the entire workpiece, while the incremental linear encoder technology provides reliable feedback to the CNC system. This results in tighter tolerances, reduced scrap rates, and significant cost savings.
Quality Control for Heavy Equipment Manufacturing
A construction equipment maker implements the VS20 linear optical encoder on their large boring machines to inspect critical dimensions on excavator boom assemblies. The robust glass scale design withstands the harsh shop floor environment, while delivering the high precision needed for QC checks. By automating measurements with the digital readout, inspection times are cut in half compared to manual methods.
Semiconductor Wafer Production
A silicon wafer manufacturer relies on this linear magnetic encoder for ultra-precise positioning of cutting tools used to slice large silicon ingots into wafers. The non-contact magnetic sensing eliminates wear and provides excellent repeatability. The ability to maintain ±5μm accuracy over long travel ranges ensures consistent wafer thickness across the entire ingot, maximizing yield.
Wind Turbine Blade Manufacturing
A wind energy company utilizes the VS20 linear absolute encoder on their massive CNC machines for milling and finishing wind turbine blades up to 80 meters long. The absolute position feedback eliminates the need for homing cycles, saving significant production time. The long measuring length and high accuracy enable precise contour milling of the aerodynamic blade surfaces, optimizing turbine efficiency.
Large-Format 3D Printing
An industrial 3D printing company integrates this glass scale encoder into their large-format additive manufacturing system to precisely control the Z-axis build platform movement. The 5μm resolution allows for ultra-thin layer deposition, while the long travel accommodates tall printed parts up to 3 meters high. This enables the production of massive 3D printed molds and tooling with exceptional dimensional accuracy.
