Computer gong processing program

1、 Start up processing:

At the beginning of each program, it is necessary to carefully check whether the tool used is the one specified in the programming instruction. When Dongguan computer gong processing starts, the feed speed should be adjusted to the minimum and executed in single section. Attention should be paid to the stop key when fast positioning, cutting and feeding. The hand should be placed on the stop key. If there is any problem, stop immediately. Pay attention to observe the moving direction of the tool to ensure safe feeding. Shenzhen computer gong processing will slowly increase the feed speed to the appropriate level. At the same time, coolant or cold air should be added to the cutter and workpiece 。
During rough machining, it should not be too far away from the control panel. If there is any abnormal phenomenon, stop the machine in time for inspection.
After roughening, pull the meter again to make sure that the workpiece is not loose. If there is a side, it must be corrected and bumped again.
Dongguan high-speed computer gongs processing in the process of continuous optimization of processing parameters, to achieve the best processing effect.
Since this process is a key process, the main dimension value of the workpiece shall be measured to see if it is consistent with the requirements of the drawing. If there is any problem, it shall be immediately notified to the team leader or programmer for inspection and solution. It can be removed after passing the self inspection and sent to the inspector for special inspection.
Clean the machine table in time after the workpiece is removed.
Processing type;
Hole machining;
Drilling processing: before drilling, the center drill must be used for positioning, and then the drill bit which is 0.5 ~ 2mm smaller than the drawing size should be used for drilling, and finally the appropriate drill bit should be used for finishing.
Reaming processing: for the reaming of the workpiece, the center drill shall be used for positioning, and then the drill bit 0.5 ~ 0.3 mm smaller than the drawing size shall be used for drilling, and finally the reamer shall be used for reaming. During reaming, the spindle speed shall be controlled within 70 ~ 180 RPM / min.
Boring processing: for the boring of the workpiece, the center drill shall be used for positioning, and then the drill bit which is 1 ~ 2mm smaller than the drawing size shall be used for drilling, and then the rough boring cutter (or milling cutter) shall be used to process the remaining machining allowance of about 0.3mm on one side. Finally, the fine boring cutter with pre adjusted size shall be used for fine boring, and the final fine boring allowance shall not be less than 0.1mm.
Direct numerical control (DNC) operation;
Before DNC NC machining, the workpiece should be clamped, the zero position should be set and the parameters should be set.
Open the processing program to be transferred in the computer for checking, and then let the computer enter the DNC state, and input the file name of the correct processing program.
Press the tape key and program start key on the machine tool, and the machine tool controller will flash LSK when machining the mechanical parts in Dongguan.
The DNC data transmission processing can be carried out by pressing the enter keyboard on the computer.

2、 Contents and scope of self inspection of workers:

Before processing, the processor must clearly see the content of the process card, clearly know the parts, shapes and dimensions of the workpiece to be processed, and know the processing content of the next process.
Before clamping the workpiece, the blank size should be measured to see if it meets the requirements of the drawing, and the placement of the workpiece must be carefully checked whether it is consistent with the programming operation instruction.
Self inspection should be carried out in time after rough machining, so as to adjust the data with errors in time. The self inspection content mainly includes the position and size of the processing parts. For example: (1) whether the workpiece is loose; (2) whether the workpiece is correctly divided; (3) whether the dimension from the processing part to the reference edge (reference point) meets the requirements of the drawing; (4) the position size between the processing parts. After checking the position and size of bulk machining parts, the rough machined shape ruler should be measured (except for arc).
After rough machining self inspection, finish machining is carried out. After finishing, the workers should check the shape and size of the processing parts: check the basic length and width of the vertical processing parts; measure the base point size marked on the drawing for the processing parts of the inclined plane.
The worker completes the workpiece self inspection.
