SW Circom



CIRCOM software is a program developed internally in order to characterize surfaces generated by flat rotation and relative geometric tolerances, such as: roundness, concentricity, planarity, coaxiality.

Circom software is installed on all roundness testers manufactured and also on the retrofits carried out on machinery built by other manufacturers, which are updated in terms of electronics and software. The program is extremely flexible since it is able to manage the simplest roundness testers with a single controlled axis, up to the most complex ones equipped with three motorized measurement axes (plate C, column Z and arm R).


The calculated parameters are: roundness, planarity, linearity, cylindricity, conicity, cone shape, concentricity, parallelism, orthogonality, angularity, run-out, total run out, thickness variation, diameter; it is also possible to analyse harmonics through FFT algorithm on roundness and planarity measures.


Gaps can be calculated, thus part of the acquired data can be automatically or manually eliminated. Circom software works with metric and English units.

There are two types of filter inside the software; for polar measurements, filters based on harmonics are used, which are: 1÷15, 1÷50, 1÷150, 1÷500 and 15÷500 ripples/revolution. While for linearity measurements, the filters used are the following: 0.25 mm , 0.8 mm , 2.5 mm and 8 mm. The two filters can be implemented through 2CR filter or the most modern Gaussiano filter


All reference calculation methods are available: for circumference LSC, MZC, MIC and MCC. For plane: LSP, MZP, MIP and MSP. For straight line: LSL, MZL, MIL and MSL.

For planarity and parallelism, it is possible to view the results in plan view and also in 3D.

For cylindricity, various display methods can be chosen: plan view, 3D with only profiles, cage, or shaded solid. All 3D views can be rotated as required.


A guided procedure allows the operator to centre and level the piece being measured.

The standard measuring cycles are directly displayed on the video. With these cycles, the piece positioning and profile acquisition phases are already set-up and the operator just needs to confirm to go to the following phase and quickly obtain the results.

For checks in series or to perform more complex calculations, it is possible to create programmable measurement cycles in order to simplify and speed up use.
