Technical Field
The invention belongs to the field of numerical control machining, and particularly relates to a method for preventing tool setting values and tool compensation values of numerical control machining from being input wrongly.
Background
When a part is numerically controlled and machined, an operator determines the relative positions of a cutter and the part and each coordinate axis through tool setting, namely a machining coordinate system, and in the process, each pair of tool values of the machining coordinate system needs to be input into a machine tool control system. In the machining process, a tool compensation value needs to be comprehensively determined according to the allowance size of parts, the tool abrasion degree, the size of dimensional tolerance and the like, and the compensation value is input into a control panel of a machine tool so as to accurately control the position of the tool to ensure the size required by a drawing. The tool setting value and the tool compensation value are calculated and manually input by an operator, are influenced by human factors, and are often over-cut and out of tolerance or scrapped due to input errors, calculation errors, operation errors and the like, so that unnecessary economic loss is caused. Such errors are generally found by observing the relative position of the tool and the part during machining, but due to the limitation of visual observation, the errors can be found by a worker who carelessly observes the errors at a large distance, and the errors of the general distance and the tolerance level of the part are difficult to find. The existing patent only realizes the judgment of the input of the lathe machining cutter compensation value, but the cutter compensation value cannot be automatically obtained, or the existing patent proposes a cutter length cutter compensation error preventing method, but has limitation on safe cutter compensation, only can judge one direction, namely, the phenomenon that the part is identified as an error when the 0 boundary is crossed, and cannot prevent the phenomenon of over-cutting the part when the cutter yielding is too large for parts with smaller machining space.

Example 1:
the part cavity shown in figure 1 is subjected to Siemens control system turning anti-error program design.
In the attached drawing 1, the processing part is a section of molded surface in the cavity, the tolerance of the wall thickness of the right end surface is +/-0.02 mm, the tolerance of the left side diameter is +/-0.075 mm, and the tolerance of the inclined surface is +/-0.1 mm. The used cutter is an elbow groove cutter, and a certain amount of cutter back-off exists during machining due to the fact that the cutter head is narrow in size and rigidity is considered. The knife compensation direction and the knife compensation amount follow the following principles: allowing the relief in the direction of no material, i.e. not over-cut, the amount of relief must not be excessive and must be matched to the allowance, while taking into account that the back of the tool cannot interfere with the part. Therefore, the X direction cutter back-off direction should be-X, the allowance of the part is 0.3, the maximum cutter back-off amount is allowed to be 0.8 (double sides), and the cutter back-off factor is considered, so that the wall thickness value of the inclined surface of the installation side is ensured, and the body is allowed to be inserted for 0.05 (double sides); similarly, the Z-direction cutter back-off direction is-Z, the allowance of the part is 0.3, the maximum allowable value of the cutter back-off amount is 0.4, and the allowable insert body is 0.05 in order to ensure the wall thickness value of the mounting edge in consideration of cutter back-off factors. From the above analysis, the correct shim ranges are X [ -0.8,0.05], Z [ -0.4,0.05], are assigned to the variables R11, R12, R13, R14 in the program, and the default anti-error subroutine module DAO _ BU _ FANG _ WU is called.
The anti-error subroutine module DAO _ BU _ FANG _ WU performs the following functions: inquiring the currently used tool number of the machine tool, respectively reading the corresponding tool number of the X, Z axes in the previous step, assigning values as R17 and R18, comparing with the interval range set in the main program, and prompting errors according to the comparison result and requiring an operator to correct the tool compensation (out of range) or continue processing (within range).
The distance between the edge of the turning tool and the minimum inner hole bus of the part can be judged in the X direction, and the minimum inner hole diameter of the part isSetting the distance A to be 10mm, so that the X-axis error-preventing point position can be determined to be (X110.0, Z25.0); the distance between the edge of the turning tool and the end face of the flange of the part (namely the Z0 position of the workpiece coordinate system) can be judged in the Z direction, and the distance A is set to be 10mm, so that the Z-axis error-prevention point position can be determined to be (X600.0, Z10.0).
For the position after the offset of the X-axis error-preventing point (X110.0, Z25.0) in the previous step is (X110.0-R17, Z25.0), and the position after the offset of the Z-axis error-preventing point (X600.0, Z10.0) is (X600.0, Z10.0-R18).
And compiling a numerical control instruction to enable the cutter to run to the error prevention point of the X axis or the Z axis after executing the error prevention point of the previous step, as shown in the attached figure 2.
And prompting an operator to use the cutter correcting blocks 3 with the length of 10mm to try to be plugged between the cutter tip and the workpiece cutter correcting face respectively, and if the cutter correcting blocks can be plugged and the residual gap is large or the cutter correcting blocks cannot be plugged completely, indicating that the cutter setting in the direction is wrong and needing to be reset, checked and changed again.
And (5) compiling a machining program section according to the size difference of the parts. The allowance of the processed part is small and can be removed at one time, so that a circulating program does not need to be compiled, only a contour processing program needs to be compiled, the allowance is layered at the position where the allowance of the part cannot be completely removed by one-time feed, one-time feed is compiled at each layer, and the movement from an upper layer terminal point to a lower layer starting point is automatically controlled by the program between each layer, so that automatic circulating processing is realized.
And at this moment, a numerical control turning program with the tool setting and tool compensation mistake proofing functions is programmed.
Example 2:
and performing FANUC control system anti-error program design on two side surfaces of the finish-milled end surface groove of the part shown in the figure 3.
Using a milling cutter 6 to machine the two sides of the end face groove with a diameter of
To ensure the surface roughness, the face milling mode is selected and programmed by using a G42 command. The tolerance of the groove width of the part is [ (24) ] 0 (+0.05) mm, and the minimum radius compensation is allowed to be made in consideration of the tool side edge wear
Because the single-side allowance of the groove width after rough machining is 0.5mm, the maximum radius compensation is allowed to reach
The correct range of the knife complement is
Values are assigned to the #511, #512 variables in the program. The depth dimension of the groove isThe margin of the groove bottom is 0.5mm, so the correct cutting compensation range of the Z axis is [ -0.025,0.5 [)]Values are assigned to the #513, #514 variables in the program, and the default error prevention subroutine module O8200 is called.
The error prevention subroutine module O8200 performs the following functions: inquiring the currently used tool number of the machine tool, respectively reading the tool radius compensation value of the corresponding tool number, comparing the Z-axis tool compensation value with the interval range set in the main program, and prompting errors and requiring an operator to correct the tool compensation (out of range) or continue processing (within range) according to the comparison result by the program.
The Z direction judges the tool nose of the milling cutter 6 and the end surface of the part, and the distance B is set to be 100mm, so that the Z-axis error-preventing point position can be determined to be (X0, Y-160.0, Z100.0).
The position after the Z-axis error preventing point (X0, Y-160.0, Z100.0) of the previous step counteracts the knife compensation is (X0, Y-160.0, Z [100.0- #2 ]).
