The traditional lathe is mainly used to test the workpiece by cutting the workpiece, that is, turning the workpiece, finely measuring the size of turning, calculating the difference between the measured value and the target value, according to the size of the difference and the positive and negative feed or retract. For CNC lathes, with the exception of a few equipped with tool setting functions, tool setting tools, countersunk blocks, or trial cuts are used. Using a special tool setting tool for external tool setting, although the precision is high, the tool must be aligned with the tool holder. Can be generally relatively heavy knife, disassembly is more laborious. Especially when only replacing the blade, using this method is slower than using a test-cutting knife. With the knife block cutter, due to the influence of various errors, the accuracy of the knife is not high. Therefore, most CNC lathes still use test-cutting workpieces. The first three steps of the procedure are the same as for the lathe's traditional countersink, but instead of changing the dial to the tool, you can use the buttons to enter the tool compensation value.
The advantages of test piece cutting tools are the low cost and high precision; the disadvantage is time-consuming, and some tools (such as oil grooved knife) are difficult to use this method to knife. Therefore, in practice, a rapid and high-precision knife setting method suitable for the outer warp, face knives or similar oil grooved knives has been found. This is a manual tool setting method that does not require trial cutting. This method can reduce the trial cutting time by 60% without the use of tool setting tools, tool setting blocks, or tool setting tools. This method can maintain the advantages of the test-cutting tool and overcome the shortcomings of the test-cutting tool.
(1) Principle. The outside diameter of the chuck can serve as a ready reference for the transverse (X-direction) tool setting, and the outer end face of the positioning block is an excellent reference for the longitudinal (Z-direction) tool setting. The size of the chuck outer diameter measured once is a constant value. The Z-origin of the program is often located on the outer end face of the positioning block, so the conventional tool setting procedures after the first try-cut and then the fine-measurement, and finally the tool compensation value are eliminated in both directions. Especially in the longitudinal direction, due to the influence of measurement error of the test piece, the accuracy of the tool setting is higher than that of the test cutting method. Since the accuracy of the mounting is not affected, the tool setting accuracy is higher than that of the standard tool setting method.
(2) Method. Because the numerical control devices of lathes are divided into two categories, the methods are divided into two categories.
1 pair of CNC lathes with absolute position detector for transverse knife setting procedure: a. Clear the X compensation value of the corresponding compensation number; b. Measure the outer diameter size of the chuck near the hole of the ring, record the D1, value (this step As long as the change of the chuck is done once, the value of D1) can be used directly afterwards; c. Turn the chuck by hand to the eye of the eyebolt against the direction of the tool nose; the left hand will place a newspaper between the tool tip and the chuck and continue Pull, the right hand to use the manual operation quickly and slowly to close the knife tip to the outer diameter of the chuck until the newspaper can not pull up, set at this time on the screen to display the X value of D2; d if the subsequent processing of the knife is small, Can not consider the amount of knife. Subtracting the screen diameter from the screen display value and subtracting twice the newspaper thickness is the value of the knife. The average thickness of the newspaper is 0.08mm, and it is 0.05mm after the partial compression. Therefore, the X-direction cutter compensation value = D2, a D1-0.1. Enter the calculated value into the X position of this knife's corresponding offset number. If the amount of knife to be processed in the future is large, the above value should be subtracted from the experience so that the amount of the knife can be input again.
Longitudinal knife setting procedure: a. Clear the Z compensation value of the corresponding compensation number; b. Turn the chuck by hand to the positioning block in the direction of the cutting edge; c. Place a newspaper in the left hand between the cutting edge and the end face of the positioning block. And keep pulling. The right hand uses manual operation to quickly and slowly approach the end of the tool nose positioning block until the newspaper is unable to move until the Z value displayed on the screen is Z1. Then the Z direction compensation value is Z1-0.05. Then enter the calculated value into the Z position of this knife's corresponding compensation number. If the amount of knife to be processed is large in the future, the above value should be subtracted from the experience and the amount of the knife before input.
2 pairs of horizontal lathes with a relative position detector: Steps a, b, c, and d are the same as those described above for the numerically controlled lathe with an absolute position detector; e “lock†the mechanical part and use a manual operation to turn the screen on The X display value is shaken to the same value as (D1 0.10); f cancel the above "mechanical lock" and manually raise the knife holder to the lateral start position; g subtract the X value in the G50 block of the program. The X value displayed on the light screen at this time is the tool compensation value, and it is input to the X position of the corresponding compensation number of this tool. If the amount of knife to be processed in the future is large, the above value should be subtracted after the experience to let the amount of the knife be input.
The longitudinal knife setting steps: a, b, c are the same as those of the numerically controlled lathe with the absolute position detector described above; d “locking†the mechanical part, and manually shifting the Z display value on the light screen to 0.05; e lift the above “Mechanical lockâ€, manual operation is used to raise the knife holder to the longitudinal start position; f Subtract the z value in the G50 block of the program from the Z value displayed on the screen at this time, which is the tool compensation value, enter it here. The Z position of the corresponding compensation number of the knife can be used. If the amount of Z-cutting to be machined in the future is large, the above value should be subtracted from the experience to re-enter the amount of the knife.
We need to pay attention to that if the origin of the program is located at Z from the end of the positioning block, then the aforementioned Z-direction tool compensation value should be added with the Z value, both of which are the same; if the tool tip cannot reach the end of the positioning block due to the claw, Z Face the knife to the available chuck, then the tool compensation value must be converted once.
