Solution Overview
Problem
Conventional warm up operation planning systems for machine tools require manual input from operators and are influenced by external environmental factors like temperature and humidity, leading to inconsistent accuracy and increased downtime and power consumption.
Innovation Solution
A warm up operation planning device that selects an optimal warm up operation program based on production plans, past working states, and environmental conditions to determine the start and finish times of the warm up operation, reducing downtime and power consumption by calculating a more precise warm up operation duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual warm up operation planning is performed by operators, then warm up operation can be executed, but inconsistency in accuracy and increased downtime occur due to environmental factors
Solution Approach 1:
The system continuously monitors actual machine accuracy during and after warm up operation, compares it with target accuracy, and uses this feedback to automatically adjust and optimize future warm up operation parameters, eliminating manual planning inconsistencies
Solution Approach 2:
The machine tool automatically performs warm up operation based on pre-stored programs selected by the control device, without requiring manual operator intervention, thereby achieving consistent execution and reducing downtime
2Manufacturing precision
If warm up operation is performed to maintain machine accuracy, then thermal displacement is reduced, but production efficiency decreases due to extended operation time
Solution Approach 1:
The system dynamically determines the warm up operation program and duration based on real-time machine state, workpiece requirements, and environmental conditions, allowing the warm up time to be optimized rather than fixed, thus balancing accuracy and productivity
Solution Approach 2:
The control device changes warm up operation parameters (program selection, duration, intensity) based on detected machine state and work requirements, enabling adaptive optimization that maintains accuracy while minimizing unnecessary warm up time
3Reliability
If excessive warm up operation is performed, then machine accuracy is maintained, but power consumption increases
Solution Approach 1:
The system performs only the necessary portion of warm up operation required to achieve target accuracy, avoiding excessive warm up, thereby reducing power consumption while maintaining machine accuracy

AI summary
A warm up operation planning device that generates a warm up operation plan for a machine tool comprises: a warm up operation program memory in which at least one warm up operation program is stored; a machining plan input unit that inputs a machining plan for a work in a predetermined period; a warm up operation program selection unit that selects the warm up operation program responsive to the state of the machine tool; a warm up operation duration determination unit that determines a warm up operation duration in response to the work; and a warm up operation planning unit that calculates start time and finish time of warm up operation based on the machining plan. The warm up operation program selection unit selects the warm up operation program responsive to the work from the warm up operation program memory.
