Features of Machine Grinding of Surfaces with a Flap Wheel

In order to obtain the necessary shape of long panels and sheaths, aircraft industry successfully uses a complex technology shaping. Grinding, as an operation in technological process, is provided after shot-peen forming before hardening. It designed ensure that roughness final aerodynamic surface meet requirements established by drawing part. To implement this technology, special installation UDF-4 (shot-impact unit) was manufactured at Irkutsk National Research Technical University. The version equipped with CNC system revolver stripping head 4-flap wheels. possibility choosing flap wheels process grinding, depending on curvature width treated surface, significantly expanded capabilities installation. elastic abrasive straight profile used production have proven themselves well both terms grinding performance tool durability. However, practice has shown due impact petals during contact zone uneven along length formed grinding. results experimental studies improved when direction movement feed changed from oncoming passing. paper presents data changes processing modes, study quality counter passing feed.
