Based on the characteristics of the precision machining industry, Dashi has created an online monitoring system for broken tools, which is committed to empowering the digital future of machining tools.。
The physical signals of current, voltage and power in the processing process are collected by high-precision connected sensors, and data signals such as processing status are obtained by interacting with the CNC system of the machine tool. Based on the big data streaming method and self-developed data processing algorithm, data visualization is realized. Processing to generate the actual tool machining load curve. After each processing is completed, the tool is monitored and alarmed by comparing the deviation with the expected processing process.
1. Tool problems faced in the machining process
Problem 1: Broken knife
Problem 2: Crash
Problem 3: stubble
Problem 4: Abnormal wear and tear
2. The role of tool radar
1. Solution for broken tool: accidental breakage of drill bits and taps during processing, and tool radar alarm to avoid subsequent secondary accidents such as tool collision
2. The solution for missing tool: if a certain tool is forgotten to be installed, it will alarm after the processing is completed, so as to prevent the problem of missing processing due to missing tool.
3. Solution for abnormal wear: The tool has not been chipped obviously, but it has been excessively worn, and problems such as burrs can be avoided by alarming.
4. The solution of secondary processing: secondary processing in some finishing positions will lead to unqualified, which can be identified and alarmed by tool radar in time.
3. Tool Radar Value
1. Traditional processing mode:
√The empirical value defines the number of tool machining times, and there are uncontrollable factors.
√Sampling is carried out for production inspection, and defective products cannot be found at the first time.
√Whether the processing technology and rhythm can be the best at present cannot be quantified.
√The machining process and tool change information cannot be informatized.
2. Tool radar processing process:
√Accurately detect tool anomalies such as broken tools, chipping, and excessive wear.
√Monitor tool condition during processing and quickly isolate defective products.
√The machining process is quantitatively analyzed through the power curve and the loss curve.
√The data can be traced, and the digital visualization management of the processing process.
Make the production line run more smoothly, reduce processing costs and substandard products, and improve production efficiency.
3. Support a variety of processing methods and machine tools
Processing method: turning/drilling/tapping/milling/boring/grinding
Machine Type: Lathe/Machining Center/Centering Machine/Grinding Machine/Special Machine
CNC system: Fanuc/Mitsubishi/Siemens/Mazzak etc.
4. Composition of tool radar digital scheme
5. Easy to install and deploy
√All use push-in terminals
√Matching servo drive adapter board
√Just 2 DI trigger signals
√Use RJ45 network port for communication
√2 hours quick installation and deployment
