Sensorized Cutting Tool Holder With Embedded Antenna Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools with communication capabilities are complicated by the need for multiple wires connecting the sensor and antenna, leading to handling difficulties and potential susceptibility to chip scattering and coolant spray.
Innovation Solution
A cutting tool holder design featuring a base with a metal member and resin, where the antenna is embedded within the resin and located away from the cutting edge, reducing wire complexity and enhancing durability by minimizing exposure to chips and coolant, while a sensor measures the tool's state and transmits data wirelessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wires are used to connect the sensor and antenna to the base, then the communication function is achieved, but the wire complexity increases and handling becomes difficult
Solution Approach 1:
The patent combines the sensor and antenna into an integrated module that is directly mounted on the base, eliminating the need for separate wire connections. The sensor unit and antenna unit are positioned adjacent to each other on the base, sharing a common mounting structure and power source, which simplifies the overall wiring architecture while maintaining full communication functionality.
2Reliability
If the antenna is positioned closer to the cutting edge for better signal transmission, then the communication range is improved, but the antenna becomes susceptible to chip scattering and coolant spray
Solution Approach 1:
The patent segments the communication system into distinct functional units: the sensor unit is positioned near the cutting edge for accurate measurement, while the antenna unit is positioned away from the cutting zone at the rear of the base. This spatial segmentation allows each component to be optimally positioned for its specific function without compromising the other, protecting the antenna from chips and coolant while maintaining signal transmission capability.
3Measurement precision
If more wires are added for sensor and antenna connections, then the measurement and communication capabilities are enhanced, but the susceptibility to chip scattering and coolant spray increases
Solution Approach 1:
The patent merges the sensor unit and antenna unit into a coordinated system mounted on the base, where both components share the same protected environment. The sensor unit measures cutting parameters while the antenna unit communicates data, and both are positioned to minimize exposure to harmful factors. The base structure itself serves as a protective barrier, enclosing the electronic components while allowing the cutting edge to remain exposed for machining operations.

AI summary
A holder may include a base, an antenna and a sensor. The base has a bar shape extended along a central axis from a first end toward a second end. The base may include a metal member and a first resin. The metal member may include a pocket that is attachable of an insert including a cutting edge. The first resin may be located closer to the second end than the metal member. The antenna may be covered with the first resin. The sensor may be located closer to the pocket than the antenna and may be wired connected to the antenna, and may be measurable a state of the base. This configuration may contribute to solving the problem that handling of wiring becomes complicated.
