What should be paid attention to in CNC machining program inspection?
CNC machining is a common processing method nowadays.In the past,it was mainly processed by ordinary lathes,but now it can be directly processed by numerical control equipment,saving time and improving precision.Therefore,this processing method is widely used in the production of mechanical equipment.in.However,due to the complexity of the CNC system,many aspects need to be paid attention to during the operation.Therefore,when programming a CNC machining center,it is necessary to check repeatedly.Avoid the wrong command of the numerical control equipment,causing significant consequences and losses.Jiexiang CNC machining center will tell you about the aspects that CNC machining program inspection needs to pay attention to.
CNC machining
1,coordinate system settings
The coordinate system setting should ensure correctness.If the equipment is not correct,even if the program moves correctly,it will cause the machine to run abnormally.In this case,running the numerical control equipment will damage the tool,machine tool and workpiece.
2,absolute,incremental
If the program written in absolute value is executed in incremental mode,or if the program written in incremental valuesis executed in absolute mode,the CNC machine will operate in an unpredictable manner.
3,plane selection
When programming circular interpolation,helical interpolation,fixed cycle,etc.,if the specified plane is not correct,the machine will not operate properly.
4,programmable mirror
When the programmable image is set to active,subsequent program actions will change greatly.

5,English,metric conversion
The unit of data must be fully confirmed before running the machine.The conversion from English input to metric input,or from metric input to English input,does not convert the workpiece origin offset,various parameters and current position.Attempting to operate with erroneous data can cause damage to tools,machine tools,and workpieces.
6,compensation function
If the command of the machine coordinate system or the command related to the return to the reference point is specified in the compensation function mode,the compensation is temporarily canceled,resulting in an unexpected operation of the machine.
7,torque limit skip
The torque limit needs to be set to valid before attempting a torque limit skip.If the torque limit skip is specified in the state where the torque limit is disabled,the execution of the move command will occur without the skip action.
8,with non-linear interpolation positioning
When positioning with a non-linear interpolation type,the path of the tool needs to be confirmed before programming.Since the positioning is performed under rapid movement,if the tool collides with the workpiece,it will damage the tool,machine and workpiece.
9,the function of the rotary axis action
When programming the normal direction,pay special attention to the speed of the rotary axis.Improper programming can cause the speed of the rotating shaft to become too fast,or the workpiece may fall off due to centrifugal force due to improper mounting of the workpiece.This can damage tools,machines and workpieces.
10,constant speed control
When the current position of the workpiece coordinate system of the constant-speed control axis is close to the origin in the constant-speed constant control,the spindle speed becomes too fast,so the maximum speed must be specified correctly.If the maximum speed is not specified correctly,some damage will be caused to the tool,machine tool and workpiece.
The above is a summary of some CNC machining program inspections summarized by Jiexiang CNC machining center.CNC machining does bring great convenience,but the requirements for use are also very high.Only after doing these precautions can we get from the basics.Going up to ensure the quality and precision of the machined parts,I hope that the introduction of Jiexiang Xiaobian can help everyone.
