Jigging equipment

Many improvements have been made to streamline performance and to reduce machine operation labor. Some of these are tensionless jigs using variable speed electric motors with built-in drag for brakes, automatic reversing equipment, and automatic temperature and level controls. These machines are widely used for goods that are easily creased, such as fabrics consisting of filament acetate, heavy filament nylon, or cotton duck. They are also convenient for small dye lots and for sampling purposes. 

Basically, the optical method uses equipment such as alignment telescopes, jig transits, and sight levels. Instruments with built-in optical micrometers for measuring displacements from a referenced line of sight enable an accurate determination of target movements, which are mounted on the machine. 

Define the special tools, processing equipment, jigs, fixtures, and other equipment required to produce the product. (General-purpose tools and equipment need not be specified because your staff should be trained to select the right tool for the job.)... 

Define the inspection aids and test equipment to be used. There may be jigs, fixtures, gages, and other aids needed for inspection. Standard measuring equipment would not need to be specified as your inspectors and testers should be trained to select the right tools for the job. Any special test equipment should be identified. 

However, these requirements go further than merely controlling the devices used for measurement. They address the measurements themselves, the selection of the devices for measurement and also apply to devices which create product features, if they are used for product verification purposes. If you rely on jigs, tools, fixtures, templates, patterns, etc. to form shapes or other characteristics and have no other means of verifying the shape achieved, these devices become a means of verification. If you use software to control equipment, simulate the environment or operational conditions, or carry out tests and you rely on that software doing what it is supposed to do, without any separate means of checking the result, the quality of such software becomes critical to product verification. In fact the requirements apply to metrology as a whole rather than being limited to the equipment that is used to obtain the measurement and therefore a more appropriate title of the section would be Control of measurements . 

While the ISO 9001 requirement applies only to quality records, ISO/TS 16949 extends retention times for many other documents because you cannot demonstrate you have or had operations under control without specifications, plans, procedures, etc. You may also need to retain tools, jigs, fixtures, test software - in fact anything that is needed to repair or reproduce equipment in order to honor your long-term commitments. 

Size separation equipment in which particles move in a fluid stream is now considered, noting that most of the plant utilises the difference in the terminal falling velocities of the particles In the hydraulic jig, however, the particles are allowed to settle for only very brief periods at a time, and this equipment may therefore be used when the size range of the material is large.

This technology was scaled-up to a 1.3 tonne plant by Anopol Ltd (Birmingham, UK). Results have shown that the technology can be applied in a similar manner to the existing technology. The ionic liquid has been found to be compatible with most of the materials used in current electropolishing equipment, i.e. polypropylene, nylon tank and fittings, stainless steel cathode sheets and a titanium anode jig. 

Cure Rate as Measured by Strength Development of Prototype Joints. Cure rate is an important factor when the expense of jigs and fixturing equipment is high or fast production rates are critical. It is also used as a quality control test to determine if the curing mechanism within the adhesive has changed from lot to lot or if it may have been spoiled by storage, moisture contamination, etc. 

Jig kg for Rh (Helmers and Merge 1998 Schuster etal. 2000). Occasionally, metal concentrations of up to 2250 jig kg Pt, 500 Jig kg Pd and 200 jig kg Rh were detected in road dust (Eckhardt and Schafer 1997 Petrucci et al. 2000 Rauch et al. 2000 Gomez et al. 2001). These levels fall within the range of those recorded in PGM-rich ores, and surpass the mean concentrations in the continental Earth s crust approximately 150-fold for Pt, 3 to 6-fold for Pd, and 60-fold for Rh (CRC 2000). Furthermore, it could be expected that the content of precious metals in road dust will continuously increase in future years concurrent with the number of cars which are equipped with catalytic converters.

The modulus of elasticity in flexure is defined in an analogous way to the tensile and compressive tests, with the strains of 0.05% and 0.25"/o again taken as the limiting values between which it is determined. This places very severe constraints on the accuracy of the test equipment and the test piece itself. For the standard test piece. 0.05% strain corresponds to a deflection of the outer surface of only 0.08 mm from its starting point. This does not make much allowance for any backlash in the test jig. lack of flatness in the test piece, or lack of alignment in any of the three loading bars.
