Dimac solutions – including its Super Gewinde tool and MCVx vision software – for the inspection and sorting of any type of fastener thread are the result of constant innovation to satisfy customers’ needs and the standards of the automotive, aerospace and automatic assembly industries.
A threading process requires a 100% analysis of each part before shipment, in order to guarantee the expected yield from an outstanding product and to prevent major economic consequences incase the part doesn’t meet the application requirements, thus avoiding annoying product recalling campaigns.
Innovative special controls from Dimac Srl include the Super Gewinde tool, which features the 360° all around optical inspection of external threads – detecting any small and localised thread defect – and the In-Thread-OK function to verify the inner threads’ presence and check the thread’s quality. What’s more, in MCV5 the In-Thread-OK function can be used in conjunction with the part programmable ejection option with which to decide what types of NOK to eject (e.g parts without thread), with a view to continuous process improvement.
The Dimac MCVx vision software also includes a special HI-LO thread function, which gives the possibility to calculate the high, low and approximate diameter of a threaded area, detecting the theoretical crests and grooves.
The thread dimensions’ tool calculates the outer, inner and flank diameter, the pitch, the bending, and the peaks count, whilst the thread angle tool searches for thread defects due to the misalignment during the threading process. The thread quality tool allows users to check the conformity of a threaded area by some crosschecks while the system automatically controls the thread to evaluate the quality according to the sample quotas and tolerances.
The angle difference option detects any steep-thread due to rolling dies misalignment – lines are drawn by the system software on the thread profile to merge crests and grooves and to calculate the angle difference with respect to the axis of symmetry of the part.
