SPC-LAB: A new way for fastener inspection 21 September 2016

Dimac Srl will be presenting the new generation of SPC-LAB – a first piece inspection mobile unit suitable for in process and post process measurements and controls directly on the shop floor – at Fastener Fair Italy.

With a renewed attention on zero defects – a priority Dimac shares with end users – SPC-LAB can inspect any kind of fasteners or mechanical component produced by cold forming, stamping or turning with accuracy of up to 0.005mm. The SPC-LAB has multiple uses: SPC controls and data collection, PPAP and reporting, direct measuring system, as well as manual sorting of pre-series without human errors.

Based on optical non-contact measurements by a high-resolution digital camera, it provides connectivity for USB gauges or high precision callipers, as well as the inspection by attributes such as surface defects, presence of a thread patch, and surface coatings.

Measuring a piece on a SPC-LAB isle unit on the shop floor is very easy and takes only a few seconds. The user simply takes the sample piece they want to measure to the nearest SPC-LAB isle unit and puts the piece into the unit without any clamping tooling. They then scan the operator badge barcode to log in, and then scan the article barcode to enable the article inspection plan. The measuring features are accessible by icons on the user-friendly unit. The user then simply presses the ‘measure’ button and all the measurements of the inspection plan will be done in less than a second. SPC data will be collected on the network and will be immediately available to the quality office to be managed by the ERP company process.

The SPC-LAB helps eliminates the need to perform single measurements on a profile projector, and helps to reduce human errors due to the use of manual callipers or micrometers. No skills are required for the operators on SPC-LAB to perform the most complex controls like measuring a radius, checking any thread dimensions, measuring a tapered shape, measuring a length between a given diameter and any shoulder edge on the piece.

SPC-LAB also features a ‘direct measuring’ option that enables it to perform any measurement on a piece without having registered an inspection plan for that part.
