And/or safety requirements measures 5
Safety requirements for large-sized CNC lathes and turning centers and/or measures shall comply with the provisions of this chapter. Furthermore, this standard does not involve
To unidentified hazards should be GB /15706.1-2007 in Chapter 5 of the T machine design.
For risk reduction through design see GB/T 15706.2-2007 of Chapter 4; to reduce the risk by taking security measures
See GB/T 15706.1-2007 Chapter 4.
Control system 5.1 General Requirements
Safety control system should meet the requirements GB /Chapter 4 15706.2-2007 T, and the requirements of this standard 5.1.1 - 5.1.10.
5.1.1 Safety and reliability of control systems
In this standard, the control of the control system safety components starting from an actuator (control means), or trigger point, ending in the final working machine
Output. (such as motor) or a configuration element.
The control system safety components include the following features, and should meet the categories defined below (see GB/T 16855.1-2008)
Claim.
--- starting or restarting, Class 1 (see 5.1.3);
--- operation stop, category 1 (see 5.1.4);
--- the maximum spindle speed is selected, the Class 2 or Class 3 (see 5.1.8);
--- emergency stop, Class 1 or 3 (see 5.1.5);
--- interlock, Class 1 or 3 (see 5.2.1.2,5.2.1.3,5.2.1.5,5.2.1.6,5.2.2 , 5.2.4);
--- interlock with lock protection class 3 (see 5.2.1.2);
--- movement axis (including low feed), Class 2 (see 5.1.8);
--- acceleration/deceleration control, Class 2 (see 5.2.1.1.1);
--- mode selection, Class 1 (see 5.1.7);
--- with self-reset control means, class 3 (see 5.1.7.2);
--- workholding, Class 1 (see 5.2.1.1);
--- tool change, category 1 (see 5.2.4).
For some control systems use different types of safety member in combination, should be at least the same level of ability to withstand failure (see
GB/T 16855.1-2008 6.3).
Verification. Check the appropriate pattern and/or circuit diagrams, visual inspection, purchased parts manufacturer provides proof of compliance with the relevant standards.
5.1.2 position control device
Position control means should meet GB 5226.1-2002 and EN894-1.1997, EN894-2.1997, EN894-3.2000 in
The relevant provisions (see 5.1.5).
Control means (eg. start means, stop means, operating mode selector switch with self-reset control means) should be located outside the danger zone (eg.
An outer enclosure or platform) of the main operation stage.
It does not allow any other position on the machine or on the selection switch mode starting device starting the work of production control work.
Hanging console to operate the machine at the adjustment mode, can be away from the main console, it can also be located outside the danger zone separate consoles
Operation of the machine, one of them optionally.
In the adjustment mode, when the machine when a variety of control methods, in any case there is only one operating mode function.
Verify. check the corresponding drawings, visual inspection.
5.1.3 start
Starting and restarting shall be as specified in 9.2.5.2 GB 5226.1-2002 and all mounted in place on the machine tool guard
And under conditions of works. Interlock device shall comply with the provisions of 5.2.1.3.
Start and restart function should meet the requirements of Class 1 GB/T 16855.1-2008 in.
Starting with the different functions of the machine work related to the selected (see 5.1.7).
When the movable guard is closed, not self-start moving member. Unless provided with pressure sensitive film on a power driven guard, the guard
After the device is closed, without restarting (see 5.2.4.3).
When the movable guard disengaged, it should be required to GB/T 19670-2005 in Chapter 6, to prevent the workpiece spindle, (faceplate,) tail sleeve
Unexpectedly cylindrical tool axis, the tool holder and a workpiece clamp dangerous operation start.
In a production mode of operation, only under conditions of closure means movable guard, using starting device starting or restarting the machine (see
GB 5226.1-2002 of 9.2.5.2).
Verification. Check the appropriate pattern and/or circuit diagrams, inspection and functional checking.
5.1.4 stop running
In operating the machine should be stopped by stopping the operation of the device implementation. Running stop (in line with GB 5226.1-2002 9.2.2
Supply power chuck) and NC control systems. motor, a workpiece (e.g., a predetermined driving stop requirement category 2), without interruption to the axis motion. Correct
Holding force required to clamp the workpiece spindle, a spindle drive should be equipped with a monitor (see GB/T 19670-2005 6.4).
The monitor should satisfy the requirements of class 3 GB/T 16855.1-2008 predetermined.
Operation stop function should meet the requirements of Class 1 GB/T 16855.1-2008 in.
When the machine stops running, disengaging movable guards should be maintained at the machine stops Class 2 (see GB 5226.1-2002 of
Under 9.2) carried out.
For the whole body is likely to enter the working area of the machine where, when restarting the machine after the operation is stopped, the operator shall take the dual action
Conducted. As. After closing the access door, then it starts the cycle; interlock function after the reset, it starts the cycle again. You should have at least one such control
Braking means located in the main operation platform, to ensure that the operator exits from the working area before restarting.
The operator should be able to observe the work area of the machine tool in the operating position.
Since the control system security component failure caused when the operation is stopped, it shall comply with Class 1 stop in 9.2 GB 5226.1-2002 pres...
