Tool Workpiece Connection TRIZ Cases

An asymmetric flute arrangement eliminates axial gaps in the cutting zone while end face teeth ensure uniform edge wear on composite laminates.

Segmented bayonet connections allow quick whirling ring replacement without removing the device, reducing downtime and improving capacity utilization.

Multi-start threads balance stress to prevent coupling failure while increasing torque capacity.

Centrally located retaining elements fix axially movable shanks in the base body, resolving high-speed rotation stability versus axial positioning precision.

Inserting a female-threaded cage into a monolithic drill body prevents liquid leakage through intersecting bores while maintaining dimensional accuracy.

Pressure screws lock tool rings in any angular position to enable stepless height adjustment.

Concave limiting surfaces strengthen the centering tip against iron impacts while preserving high drilling speed.

A rotary cutting tool uses a threaded sleeve to clamp the head axially.

Spiral driven surfaces on a replaceable cutting head provide self-locking retention, eliminating complex torque transmission mechanisms.

A rotating shaft tool integrates a circumferential groove with adjustable spreading elements for radial adjustment.

Segmenting the top plate into a fixed rim and removable inner section resolves core jamming by exposing trapped material for easy extraction.

Expanding cross-sectional grooves in a one-piece drill head act as a check valve to prevent secondary comminution and improve drilling removal efficiency.

A face mill with a convex main cutting edge and reduced setting angle distributes forces evenly, preventing vibrations at high speeds.
