Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If coolant-lubricant fluid is sprayed on the cutter, then cooling and lubrication are provided, but the fluid has hard time reaching the cutting edge effectively
Solution Approach 1:
The support body face is segmented into multiple radial zones with grooves at different radii, allowing coolant to be distributed to different radial positions independently. This segmentation enables effective coolant delivery to the cutting edge by creating multiple pathways that overcome the problem of coolant not reaching the cutting zone effectively.
Solution Approach 2:
The invention transitions from conventional axial coolant delivery to radial coolant distribution through grooves etched on the support body face. By adding the radial dimension to coolant flow paths, the system effectively delivers coolant from the center to the periphery where the cutting edge operates, solving the delivery effectiveness problem.
2Ease of operation
If radial grooves are provided on the support body to guide coolant, then coolant distribution is improved, but the solution is poorly adapted for cutter discs with varying tooth arrangements
Solution Approach 1:
The support body is designed with a universal coolant distribution system consisting of multiple concentric radial grooves that can serve any tooth arrangement. The grooves are positioned at different radii and can be selectively used depending on the specific cutter configuration, making the support body adaptable to various tooth numbers and patterns while maintaining effective coolant delivery.
Solution Approach 2:
The invention uses variable groove parameters (radius, depth, width) to adapt the coolant distribution system to different tooth configurations. By changing these geometric parameters, the same support body design can effectively cool cutters with different numbers and arrangements of teeth, enhancing versatility.
3Temperature
If curved grooves are used to guide coolant radially, then coolant reaches the cutting edge, but the support body has a preferred rotation direction requiring specific tooth arrangement
Solution Approach 1:
The invention employs asymmetric groove patterns where grooves at different radii have different orientations and curvatures. This asymmetric design allows the coolant distribution system to adapt to the rotation direction and tooth arrangement, enabling effective cooling without imposing a strict preferred rotation direction constraint on the cutter operation.
4Adaptability or versatility
If multiple radial grooves are added to distribute coolant to different teeth, then cooling coverage is improved, but the support body design becomes more complex
Solution Approach 1:
The support body incorporates a porous or micro-channeled structure that allows coolant to distribute radially through multiple pathways. This porous approach provides extensive coolant distribution coverage without requiring large, complex macro-grooves, thereby maintaining structural simplicity while achieving broad cooling coverage across different tooth configurations.

AI summary
Cutter disc which comprises: a disc-shaped support body (2), equipped with two faces (3) delimited peripherally by an outer perimeter edge (4) and centrally by a through hole (5) for coupling with a chuck of a tool-holder; and a plurality of teeth (6) distributed along the outer perimeter edge (4) of the support body (2). Each of the faces (3) of the support body (2) comprises an intermediate area having a plurality of discrete protuberances (7), made integral with the support disc (2) and of the same material as the latter, distributed radially and circumferentially and separated from one another by a recessed network (8) of intercommunicating channels, which can guide a cooling fluid released on the faces (3) of the support body (2) towards the teeth (6) of the cutter disc. The cooling fluid is able to reach substantially each of the teeth (6) of the cutter regardless of the number and distribution of the teeth (6) themselves along the outer perimeter edge (4). Another object of the invention is a method for obtaining a cutter disc having the above-reported characteristics.
