Groove Machining Program Balancing Tool Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current groove machining by continuous drilling faces challenges in stabilizing the drilling tool due to unbalanced cusp height and increased machining time, leading to tool vibration and reduced service life, as prior techniques fail to effectively address these issues.
Innovation Solution
A program generation device that calculates drilling positions and machining time based on specified cusp height and tool radius, ensuring a balanced removal stock bias, thereby stabilizing the tool and reducing machining time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the number of drilling operations is increased to reduce cusp height, then manufacturing precision is improved, but machining time increases
Solution Approach 1:
The system dynamically changes drilling parameters including hole pitch, number of drilling passes, and spindle speed based on the calculated cusp height requirements, optimizing the balance between precision and time
Solution Approach 2:
The machining program is generated dynamically by automatically calculating the optimal number of holes and drilling parameters based on the groove shape and desired cusp height, rather than using fixed predetermined values
2Ease of operation
If drilling is performed in sequence from one direction, then ease of operation is improved, but reliability deteriorates due to tool vibration and unstable machining
Solution Approach 1:
The system introduces asymmetric machining patterns by varying the drilling direction and sequence, machining holes from different directions rather than always proceeding linearly from one end, which balances the removal stock distribution and reduces tool vibration
Solution Approach 2:
The system pre-calculates the optimal machining sequence and hole positions before generating the machining program, determining the best drilling order in advance to prevent tool instability during actual machining operations

AI summary
A program generation device generates a program for controlling machining of a groove which is performed by machining a plurality of holes on a workpiece. The program generation device receives specified values including a tool radius, a groove shape (a length of the groove), and a cusp height and calculates positions of the plurality of holes based on the specified values which are received. Then, the program generation device calculates a machining order of the plurality of holes based on the specified values and respective values calculated by a hole machining set value calculation unit so that a bias is not generated in a removal stock for a tool in machining.
