Modular Insert Seat for High-Feed and Finishing Cutting Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indexable rotary cutting tools require separate tool bodies for high-feed machining and finishing due to their distinct cutting insert shapes, leading to increased inventory burdens and inefficiencies in three-dimensional machining processes like mold making.
Innovation Solution
A tool body design that allows for the remountable installation of two types of cutting inserts with different shapes, specifically a first cutting insert with a hexagonal shape for high-feed machining and a second cutting insert with a rounded quadrangular shape for radius cutting, using a modular insert seat configuration with varying surface contact points for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cutting insert with a substantially linear major cutting edge is used for high-feed machining, then cutting efficiency is improved, but the ability to perform finishing operations deteriorates
Solution Approach 1:
The cutting insert is designed with a unique geometry that enables it to perform both high-feed roughing operations and finishing operations with the same tool, eliminating the need for separate inserts for different machining stages
2Reliability
If separate tool bodies are used for high-feed machining and finishing operations, then each operation can be optimized, but inventory control complexity increases
Solution Approach 1:
The invention merges the functionality of multiple specialized tool bodies into a single universal tool body that can accommodate cutting inserts for both high-feed machining and finishing operations, thereby simplifying inventory management while maintaining operational optimization
3Adaptability or versatility
If multiple types of tool bodies are required for different cutting operations, then functional versatility is achieved, but cost and maintenance burden increase
Solution Approach 1:
A single tool body design is created that can accommodate various cutting inserts for different operations through a standardized mounting mechanism, providing functional versatility while reducing the number of tool bodies needed and lowering associated costs and maintenance requirements

AI summary
The present invention relates to a tool body 1 provided with at least one insert seat 2. The insert seat 2 comprises a bottom wall surface 4 and a side wall surface 5. The side wall surface 5 comprises a first side wall surface 5a and a second side wall surface 5b. The first side wall surface 5a comprises at least two surface portions 5a1, 5a2. The first surface portion 5a1 is a curved surface in a recessed shape, and the second surface portion 5a2 is a curved surface in a recessed shape having a greater curvature radius than that of the first surface portion 5a1 or a flat surface. The two surface portions 5a1, 5a2 both come into contact with a cutting insert.
