Lab Manual: Study of CNC Laser Cutting Machine
Objective:
To understand the working principle, components, and operation of a CNC laser cutting machine.
Apparatus Required:
CNC laser cutting machine, design software (e.g., CorelDRAW or AutoCAD), material sheet (wood, acrylic, etc.), safety goggles.
Theory:
CNC (Computer Numerical Control) laser cutting is a non-contact thermal process that uses a focused laser beam to cut materials with high precision. The laser melts or vaporizes the material, and
Como tema actual hemos escogido el problema de la vivienda que tenemos en España. Se trata de una situación que afecta a miles de personas, especialmente a jóvenes y familias trabajadoras, y que se ha convertido en uno de los grandes retos sociales de nuestro tiempo. Tal y como sabéis, la última semana ha tenido lugar una manifestación importante relacionada con este tema: la movilización bajo el lema “Canarias tiene un límite”. Una de las principales razones por las que la gente ha
Giovanni Boccaccio nasce nel 1313, probabilmente a Certaldo, vicino Firenze. È figlio illegittimo di Boccaccio di Chellino, un ricco mercante al servizio della potente compagnia bancaria dei Bardi di Firenze. Viene riconosciuto dal padre, compie i primi studi a Firenze e viene avviato alla carriera mercantile e bancaria. Nel 1327, a soli 14 anni, si trasferisce a Napoli con il padre, per seguire le attività bancarie dei Bardi presso la corte angioina. Qui inizia a esercitare il mestiere di mercante
Duran Duran – Rio (1982) Representation: Ethnicity is largely absent or tokenised. The video features a white British band surrounded by exotic, tropical imagery, filmed in locations like Antigua. Women featured are racially ambiguous or white, and largely passive. Key Example: The tropical backdrop is used to enhance the band’s glamour, but the local culture or people are not acknowledged — the setting becomes a backdrop for white luxury. Theory Link: Said’s Orientalism — the exotic is...
1. In Cat’s Dream, Pablo Neruda uncovers the latent soul of ordinary things by meditating on the quiet, mysterious life of a cat. He sees the cat not just as an animal, but as a symbol of peace, grace, and silent wisdom. The poet marvels at the cat’s detachment from the chaos of the human world. By observing its stillness, poise, and independence, he discovers a deeper essence within the mundane. Neruda believes that even simple, everyday creatures possess an inner richness that often goes unnoticed....
1. Investigate the Relationship Between Mass and Weight
What to do step-by-step:
Attach the spring balance or newton meter securely so it hangs vertically. Place the first known mass (e.g., 100 g) on the balance hook. Wait for the reading to stabilize and record the weight (in newtons). Repeat steps 2-3 for several masses (e.g., 200 g, 300 g, 400 g). Plot a graph of weight (N) against mass (kg).
Variables:
Independent: Mass (kg)
Dependent: Weight (N)
Control: Location (keep experiment on Earth, constant
Speed = Distance ÷ Time Distance is in metres (m). If given in kilometres (km), multiply by 1000 to get metres. Time is in seconds (s). If given in minutes, multiply by 60.
Acceleration = Change in velocity ÷ Time Velocity in metres per second (m/s). If in km/h, divide by 3.6 to convert to m/s. Time in seconds (s).
Force = Mass × Acceleration Mass in kilograms (kg). If given in grams (g), divide by 1000. Acceleration in m/s².
Weight = Mass × Gravitational field strength (g = 9.8 N/kg)
Density
