Turret Origin Guidance Display for Accurate Tool Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for angular position adjustment of a turret in machine tools are complex and difficult for operators to perform, especially when there is a deviation between the set and actual origins, requiring frequent and accurate alignment for smooth tool transfer between the turret and spindle.
Innovation Solution
A guidance display method is implemented on a display unit to instruct operators through step-by-step instructions, including moving the spindle near the tool transfer position, observing tool tip runout, raising the spindle to a non-interfering position, and adjusting the turret to reduce runout, simplifying the angular position adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual angular position adjustment is performed without guidance, then the operator can adjust the turret origin, but the procedure is complicated and difficult to perform
Solution Approach 1:
A display unit is introduced as an intermediary device that provides step-by-step guidance instructions to the operator during the angular position adjustment process. The display unit mediates between the complex adjustment procedure and the operator, breaking down the process into manageable steps with clear instructions, thereby making the complicated procedure easier to follow and execute while maintaining measurement precision
2Productivity
If the turret origin is not accurately aligned, then the angular position determination is simple, but tool transfer between turret and spindle becomes inaccurate
Solution Approach 1:
The angular position adjustment procedure is segmented into multiple discrete steps, each displayed separately on the display unit. The process is divided into: (1) moving the spindle to a specific position, (2) observing tool tip runout, (3) raising the spindle to a non-interfering position, and (4) turning the turret to reduce runout. This segmentation makes the complex adjustment procedure more manageable and easier to execute accurately
3Measurement precision
If frequent origin recovery is performed to maintain accuracy, then tool transfer precision is maintained, but operational time is lost
Solution Approach 1:
The display unit provides real-time feedback to the operator during the origin recovery process, showing step-by-step instructions and guidance. This feedback mechanism ensures that the operator can perform the adjustment correctly on the first attempt, reducing the need for repeated origin recovery operations and minimizing time loss while maintaining alignment accuracy

AI summary
A display unit is controlled to display guidance such as to instruct an operator to move a spindle up and down near the Z-axis position at which the tool is transferred between a grip and the spindle and to observe a lateral movement of the tip of a tool at the same time. Then, when the tip of the tool moves laterally, the display unit is controlled to display guidance to instruct the operator to raise the spindle and turn a turret so as to reduce the lateral movement of the tip of the tool.
