Master-Slave Network for Machine Tool Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for core drilling machines and auxiliary devices lack flexibility, particularly in communication between the core drilling machine and auxiliary devices, which requires intervention from a mobile device for parameter setting and control.
Innovation Solution
A method where the main machine tool, auxiliary devices, and mobile device are designed with transmitting and receiving devices, allowing the main machine tool to act as a master and auxiliary devices as slaves, enabling parameter setting and communication without mobile device intervention, using open-loop and closed-loop control to adjust parameters based on received signals.

Engineering Contradiction Analysis
1Ease of operation
If a mobile device is used as the master to control the core drilling machine and auxiliary equipment, then the system can be operated remotely and users are protected from dirt and noise, but the system lacks flexibility and communication between the core drilling machine and auxiliary equipment is not possible without the mobile device
Solution Approach 1:
The system is segmented into multiple independent communication channels: the mobile device can communicate with the master machine tool independently, and the master machine tool can communicate with auxiliary devices independently. This segmentation allows the system to operate remotely via mobile device while also enabling direct communication between machine components, thus resolving the contradiction between ease of operation and system flexibility.
Solution Approach 2:
The master machine tool acts as an intermediary between the mobile device and auxiliary devices. It receives control signals from the mobile device and can also independently communicate with auxiliary devices to coordinate their operation. This intermediary role enables both remote operation capability and direct machine-to-machine communication, addressing the flexibility issue.
2Extent of automation
If the mobile device acts as the master in the network, then remote control is enabled, but communication between the core drilling machine and auxiliary equipment requires mobile device intervention
Solution Approach 1:
The communication architecture is segmented into two independent layers: a remote control layer (mobile device to master machine tool) and a local coordination layer (master machine tool to auxiliary devices). This segmentation simplifies the communication protocol by allowing each layer to operate independently with its own simple protocol, reducing overall system complexity while maintaining remote control capability.
3Adaptability or versatility
If auxiliary devices are connected to the mobile device directly, then each device can be controlled independently, but the system topology becomes rigid and communication between machine tools is not possible
Solution Approach 1:
The system merges the control functions by designating the master machine tool as an intermediate controller that receives commands from the mobile device and coordinates auxiliary devices. This combining of control functions at the master machine tool level enables both independent device control and machine-to-machine communication, while maintaining a flexible topology where the master machine tool can adapt its role based on operational needs.

AI summary
A method for operating a system (1) is described, wherein a main machine tool (5), at least one auxiliary device (10, 25, 35) and a mobile device (45) are each embodied with a sending and receiving device (3, 13, 28, 38, 46). Said method comprises the following steps: selecting the main machine tool (5) as master in a network; selecting the at least one auxiliary device (10, 25, 35) as slave in the network; sending at least one signal from the at least one auxiliary device (10, 25, 35) to the main machine tool (5); setting at least one parameter on the basis of the at least one received signal; sending at least one further signal from the mobile device (45) to the main machine tool (5); and setting at least one parameter of the main machine tool (5) and/or of at least one auxiliary device (10, 25, 35) on the basis of the further signal from the mobile device (45). A system (1) for performing such a method is also described.
