definition of spark out - Industrial/Mfg engineering .

12/12/2003· A case in point is grinding a part on a Blanchard Grinder going from rough to flat and parallel. When the surface clears you make a very small adjustment on the infeed and let it "spark out". This is to average out any imperfections caused by the grinding wheel or machine.

Spark erosion grinding systems remove metal stock using AC current. The process relies on EDM technology, which allows manufacturers to arc-grind profiles onto metal parts. Aerospace and other professionals often opt to repair and reshape parts using spark erosion grinding rather than replacing expensive, specialized components.

Can fabricators really automate grinding?

For instance, certain tank grinding applications today use an overhead gantry-mounted belt-grinding system that traverses across a workpiece more than 12 feet long. At the same time, traditional articulating-arm robots can be integrated to use not only disc media, but also change over media when required, as the operation progresses from weld removal to surface conditioning.

Eight tips for effective grinding - The Fabricator

Just as different cutting tools are designed for different applications, different grinding discs are designed for different metals. For instance, some welds in high-strength, abrasive-resistant steels have been known to be ground down best with specialized discs that can "chisel" or "chew" away at the hard, high-tensile weld metal.

The spark-in and spark-out time constants were also identified and used in a grinding force and infeed model to simulate the plunge grinding process. These simulations showed that, due to the combination of reduced forces and time constants when using a grooved wheel, improvements in overall plunge cycle time of up to 30% could be achievable.
