Initially, taper cone-shaped devices were made from aluminum by computerized numerically controlled (CNC) turning as manufacturing technique using a lathe [47]. [Pg.225]

When the pump is turned off, the condensation nuclei count decreases by ventilation and plate-out to that observed before the sampling process. Thus, there must be a process during the sampling period that shifts the particle size to a size detectable by the CNC. The "pump effect" has further been found to be proportional to the S(>2 concentrations (Figure 6). It was not observed when... [Pg.375]

Simply put, instead of turning handwheels as is required by conventional machines the CNC machine control unit (MCU) sends a motion signal via a controller board to a servo motor attached to each machine axis. This causes the servo motor to rotate a ballscrew attached to the table, cross-slide or column, causing it to move. The actual position of the axis is continuously monitored and compared to the commanded position with feedback from a transmitter attached to the ballscrew. The ballscrews have almost no backlash, so when the servo reverses direction there is almost no lag between a commanded reversing motion and corresponding change in slide direction. [Pg.173]

When a CNC machine tool is first turned on, it does not know where the axes are positioned in the workspace. Home position is found by the power up/restart sequence initiated by the operator. This power up/restart sequence drives all three axes slowly towards their extreme limits of travel, which can be -X, +Y, h-Z. As each axis reaches its mechanical limit of travel, a limit switch is activated. This signals to the control system that the home position of each axis has been reached. Once all three axes have stopped moving, the machine is said to be homed. The machine co-ordinates are synchronised with the machine control system. [Pg.179]

The machine used for the turning is a JOBBERXL CNC lathe having the control system FANUC Series Oi Mate-Tc and equipped with maximum spindle speed of 3,500rpm, feed rate 15-20m/rev and KVA rating -16 KVA. For generating the turned surfaces, CNC part programmes for tool paths were created with specific commands. [Pg.200]

North Fork says its bullets begin as a bar of solid copper and are individually turned on a CNC lathe. Pure copper is more difficult and time-consuming to machine, but it holds together better under impact than gilded copper jackets. ... [Pg.171]
