Joined Workpiece Machining Through Support Sections at Eccentric Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools struggle to smoothly machine joined workpieces that are eccentrically joined, as the joint portion may not fit through the support section, hindering efficient machining.
Innovation Solution
A machine tool with a grip section and a support section that allows the joined workpiece to be supported at an inner peripheral surface with a predetermined width, enabling the workpiece to be rotated for machining. The machine tool includes a joint portion processing control means to process the joint region and a movement control means to move the workpiece relative to the support section, ensuring smooth machining even when the workpieces are eccentric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the joint portion is not processed to reduce its outer diameter, then the machining process is simpler, but the joint portion cannot pass through the support section when workpieces are eccentrically joined
Solution Approach 1:
The joint portion is processed in advance to reduce its outer diameter to a predetermined size before the machining operation. This preliminary processing ensures that the joint portion can pass through the support section during subsequent machining, even when workpieces are eccentrically joined, thereby enabling smooth machining operations.
2Productivity
If the outer diameter of the joint portion is reduced to pass through the support section, then machining can proceed smoothly, but additional processing steps are required
Solution Approach 1:
The joint portion processing is performed as a preliminary step before the main machining operation. By reducing the outer diameter of the joint portion in advance, the system ensures uninterrupted machining flow and prevents downtime during the main machining process, thereby improving overall productivity despite the additional initial processing time.
3Adaptability or versatility
If the support section width is increased to accommodate eccentric joint portions, then no processing of the joint portion is needed, but the machine tool structure becomes more complex
Solution Approach 1:
Instead of increasing the overall width of the support section, the invention applies local quality by selectively processing only the joint portion to reduce its outer diameter. This localized approach allows the support section to maintain its original dimensions while still accommodating eccentric joint portions, avoiding the need for a more complex support section structure.

AI summary
A machine tool includes: a joint portion processing control for controlling the processing of the joint portion in a joined workpiece such that a first workpiece is gripped by a grip section, and a predetermined region extending from a joint portion of a joined workpiece toward a second workpiece is processed over a range of not less than a predetermined width to have an outer diameter of not more than an outer diameter of the first workpiece; and a movement control for controlling the movement of the joined workpiece so as to slidingly move the joined workpiece relative to the support section, from a state in which the first workpiece is supported by the support section, up to a state in which the second workpiece is supported by the support section.
