Laser Calibration: Linear Axis
We conduct Laser calibration of Linear Axis confirming to ISO 230: 2 - 2014 standard.
Measurement and Optimisation of below Parameters.
- Positioning error (A)
- Positioning repeatability (R)
- Systematic positioning error (E)
- Reversal (B) (Backlash)
- Mean reversal
- Range of mean bidirectional positioning error (M)
Methodology
- Set of 5 repetitions of ‘As Is’ condition to understand behaviour and abnormality in the axis.
- Set of 2 repetitions by changing existing pitch error compensation and Backlash compensation values to ‘Zero’ to understand pitch error and wear pattern without correction.
- Set of 5 repetitions after putting new software derived Pitch error compensation and Backlash compensation values.
- Set of 1 repetition to find out Feed Backlash value.
- Set of 2 repetitions after correction of Feed Backlash for verification.
- Sr. No. 4 and 5 are applicable in case of Fanuc and Mitsubishi Controllers.

Scope of Geometry Measurement using Alignment Laser System XK10
Geometric Measurements
Level:
Measurement of level with respect to gravity, or to another machine surface. This is typically used to align machine stages and to check gradual distortion of machine structure over time. It can also be used to level one machine relative to another.
Straightness:
Measurement of vertical and horizontal straightness along an axis. Used for all machine builds to ensure accuracy when mounting and aligning stages and guideways.
Squareness:
Measurement of the orthogonality of two axes. This would typically be used to ensure that machine arms and beds are at right angles, to align machine rails, or when squaring separate machine assemblies.
Flatness:
Measurement of vertical deviation along a machine bed, rails, or other machine planes. A versatile mode that can measure continuous or interrupted planes, for example to measure height differences between fixtures or machine sub-assemblies.
Parallelism:
Measurement of the straightness deviation or overall misalignment angle between two nominally parallel axes. It is typically used during the manufacture of machine tool structures.
Rotational Measurements
Straightness:
Vertical and horizontal straightness measurements can be made along the axes of rotary tools and small machine tools, as well as to align machine sub-assemblies, such as a bar feeder with a lathe.
Coaxiality:
Measurement of the deviation of one rotating center from another. This is typically used for alignment of rotary spindles or chucks, for example when building a lathe.
Spindle direction:
Measurement of the angle at which a spindle or chuck is pointing. This can be used for any spindle or chuck alignment, to ensure that it points in the same direction through a full 360° rotation.
