Nowadays, manual tasks are carried out punctually in isolated operations and with few pieces in the CNC workshop, but before practically all actions were carried out manually.
Before NC and later CNC machining arrived, drilling a tube was done by placing said tube in the machine tool vise to hold it, selecting the rotation speed of the drill and activating the spindle. Placement of the drill bit on the spindle, activation of the spindle, placement of the workpiece under the drill press, machining of the hole and also turning off the spindle were done manually. And as a greater number of parts needed to be machined and more difficult machining actions were carried out, human fatigue and possible human errors increased and, on the other hand, productivity decreased.
NC machining already represented an advance in this sense, because it made it possible to control the machine tool by means of the perforated tape, which contained the movements made by the machine in relation to the coordinate axes that determined the movement of the cutting tool. In this way, human intervention was not necessary so that the operator could do other tasks and productivity increased.
What improvements are achieved in the CNC workshop?
When the CNC workshop Many improvements are obtained, since many processes are automated. These are the benefits they can bring:
- It improves automation compared to numerical control without a computer. This means that everything works automatically except when necessary in specific cases, such as for repair or prototype work. Increases productivity because the machines can run 24 hours a day in the CNC workshop.
- More consistency and precision of parts, because CNC machines have incredible precision and repeatability specifications and many identical workpieces can be made.
- More flexibility; They are machine tools that are controlled by a computer program and new machining can be done that contains small changes to a previous saved job, allowing quick adaptations to be made to any part.
- More security; Since there is minimal operator interaction with the machine in almost all movements in the CNC workshop It causes fewer workplace accidents to occur. The operator no longer has to intervene to change heads, stop a movement or load material.
The machining of CNC workshop It allows you to do practically everything and in an automated way, although the operator's task is necessary for some operations such as checking measurements and adjustments so that the CNC machine continues working.
