Predictive maintenance is the process of using sensor data to infer the state of a machine, and detect flaws or failures before they happen from that sensor data [1, 2].Predictive maintenance is a rising trend in virtually all industry branches, ranging from bearing fault detection [], gear wear detection [] or piston wear in reciprocating machines [] amongst many other . The Mel Spectrograms given by librosa are image-like arrays with width and height, so you need to do a reshape to add the channel dimension. Define the input and expected output # It looks stupid but that way i could convert the panda.Series to a np.array x = np.array(list(df.mel)) y = df.speaker_id print('X shape:', x.shape) During the audio collection, the CNC program of machine tool for each cut was designed to collect a signal with first five seconds of ambient noise followed by another five seconds of only machine tool noise and later the actual cutting sound. The signals were collected at a sampling rate of 44100 Hz. 3.

This paper introduces a novel method for predicting tool wear in CNC turning operations, combining ultrasonic microphone arrays and convolutional neural networks (CNNs). The end-milling operation was conducted using a DAVID 3020 CNC machine from David Motion Technology. Three flutes of square-end mill of ∅1–∅5 were used in the experiment. An Audio Technica AT2020+ microphone and Cornell University Raven Lite [ 17 ] were used for recording the machining sound.
Tool health monitoring (THM) is in great focus nowadays from the perspective of predictive maintenance. It prevents the increased downtime due to breakdown maintenance, resulting in reduced production cost.

Inkscape is a free and open-source CNC software commonly used in laser cutting for its great 2D design tools. And for all the same reasons, it’s great for 2D CNC cutting as vectors work perfectly for projects with text and image designs. For more complex and advanced design projects, using Inkscape (free) or Adobe Illustrator (.99/month) can be easier for the initial . CNC Machine works with CAD/CAM software and G code for automated machining. The programming begins using CAD software to create a digital design. Then CAM translates the CAD-based design and generates the necessary parameters and instructions. For specific operations, CNC machines are equipped with different tools and accessories.
