CNC Torch Bevel Head for Plow Bolt Hole Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cutting plow bolt holes in workpieces require separate steps and torch adjustments, making the process time-consuming and inefficient, especially when multiple holes need to be cut.
Innovation Solution
A method that recognizes plow bolt holes in computer-aided designs and generates a tool path for a CNC machine to cut both the inner and outer shapes of the hole consecutively without interrupting the torch flame, using a bevel head tool assembly that allows simultaneous rotation around multiple axes to create a beveled cut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate steps and torch adjustments are used to cut plow bolt holes, then cutting precision can be maintained, but cutting time increases and efficiency decreases
Solution Approach 1:
The patent combines multiple cutting operations (outer shape cutting and inner shape cutting) into a single continuous torch operation. The bevel head tool assembly enables the torch to cut both the outer cylindrical shape and the inner square shape without interruption, merging what were previously separate steps into one efficient process that maintains precision while improving productivity
Solution Approach 2:
The bevel head tool assembly introduces dynamic capability to the cutting system by enabling simultaneous rotation around multiple axes (vertical axis for outer shape, horizontal axis for inner shape). This dynamic multi-axis rotation allows the torch to adapt its cutting angle and orientation continuously, maintaining cutting precision while eliminating the need for manual torch re-adjustment between operations
2Manufacturing precision
If torch re-adjustment and re-ignition are performed for each hole, then cutting quality can be ensured, but cycle time increases
Solution Approach 1:
The patent implements continuous useful action by maintaining the torch flame throughout the entire cutting process. The bevel head tool assembly allows the torch to transition smoothly between cutting the outer shape and inner shape without extinguishing or re-igniting the flame, ensuring cutting quality is maintained while eliminating the time loss associated with repeated torch ignition and adjustment
3Device complexity
If a simple cutting torch is used, then device complexity is low, but the ability to cut complex shapes consecutively without interruption is limited
Solution Approach 1:
The bevel head tool assembly adds dynamic multi-axis rotation capability to the cutting torch, enabling it to perform complex cutting operations (outer cylindrical shape and inner square shape) consecutively without interruption. This dynamic capability allows the torch to automatically adjust its orientation and cutting angle, providing the versatility needed to cut complex plow bolt hole shapes while maintaining reasonable device complexity

AI summary
A method for cutting a plow bolt hole in a work piece using a cutting torch includes receiving a computerized part file including elements representing holes to be cut in the work piece. An element is selected and assigned a plow bolt hole identity. The selected element is associated with an aspect of an inner shape and an aspect of an outer shape of the plow bolt hole. A tool path is developed for the cutting torch that accounts for the aspect of the inner shape and the aspect of the outer shape and is associated with the selected element. Instructions are output to a computer numerical control (CNC) machine to move the cutting torch along the tool path so as to cut both the inner shape and the outer shape of the plow bolt hole in the work piece consecutively without interrupting a flame of the torch.
