All Dimac automatic machines are divided into a part feeding section, a test section, and an unloading section with one or more outlets.
The design of the machine starts from the need for measures and controls and then the selection of the correct stations to be placed along the test section.
Optical measures and dimensional checks from profilometer automatic interpretation of Black and White images obtained from backlighting.
Part measures (in SPC) or dimensional checks (in 100% sorting machines) of any dimension, real or virtual, that could appear by the projection of the shade of the part on the camera.
Tools: lengths, diameters, angles, co-axiality, linearity, parallelism and perpendicularity, shape’s conformity, presence of burrs on the edges, hexagon dimensions… The measure could be managed also between virtual elements (projection of sides, geometrical barycenter of shapes, …) or in reference to a fixed part of the machine (i.e. penetrators to measure the recess depth). Any measure could be compared with a range of tolerance to verify its conformity. Application on about 500k different shapes guarantees a wide range of solutions.
Any top camera on automatic SPC; the top camera on glass table machines MCV5 and MCV6; the top camera on metal table machines MCV0, MCV1, MCV3, MCV4 only to check longitudinal open holes.
Possibility of various combinations of camera resolutions, optics (telecentric, quasi-telecentric, zoom), and lighting to empathize performance in precision (up to 0,005 microns), flexibility or productivity (up to 1000 pcs/min), optimizing costs on the actual production needs.
Ancillary: Filters to avoid dirty influence on the measures, possibility of Boolean operators (i.e. for asymmetrical parts under control or the combination of more than one results), lengths between different cameras, pairing with penetrator bits, pairing with 360° station, MSA and metrological verification reports.
All the tools are integrated into the Dimac proprietary software MCVx and SPCx, which could be upgraded on customer request.

Coupled with a dimensional side camera to manage optical measurements. Low cost and space-saving combination of a wide range of tests, the main difference with the split solution is that it is impossible to lift the part in front of the camera: the part is laid on the dial during the check. Thanks to the patent-pending damper key engaging insert, the false rejects are very low.
