1) Learn the trench type

Learn three main types of grooves is very important, they are: outer grooves, facing grooves and the via trench. Cylindrical groove most easily processed, because gravity can help chip removal and coolant. In addition, cylindrical grooving is visible to the operator, and can be relatively easily check the processing quality directly. However, the design or the workpiece holding some potential barriers must be avoided. Generally, when the grooving tool tip is maintained at slightly below the centerline, cutting the best results. Hole grooving relatively similar to the outer diameter of the slots, except that the application of coolant and chip more challenging. For the inner hole grooving, the tool tip is slightly higher than for optimum performance when the centerline. Processing facing grooves, the tool must be able to move in the axial direction, and flank radius of the tool must be matched with each other machining radius. When face grooving tool nose position slightly above the centerline of the best processing results.

2) Machine tools and applications

The basic elements of the grooving, the type of machine design and technical conditions also need to be considered. Some of the major machine tool performance requirements include: having sufficient power, ensure that the tool can be run in the correct speed range, will not stall or jitter; sufficiently high rigidity, to be completed by machining requirements, will not flutter; It has a sufficiently high coolant pressure and flow, helping chip; a sufficiently high accuracy. In addition, in order to process the correct shape and size of the grooves on the machine for proper calibration commissioning is also crucial.
