1) during the molding of high precision parts, use the tool spindle of the dial gauge testing, it still beat control in less than 3μm, if necessary re-clamping or replacing toolholder systems;
2) whether it is first machined parts, machined parts or periodically repeated, must be in accordance with the pattern before machining processes, procedures and tools to adjust the card carried by the knife, checked for piecewise program, especially for the program tool length Compensation and radius compensation at the time necessary to do test cut;
3) single-stage trial cut, rapid override switch must be placed in a lower range;
4) The first time you use each tool, you must first verify its actual length and the value of the compensation is consistent;
5) The program is running, it should focus on observation of several CNC system display;
6) coordinates display: can understand the current position of the tool motion point in the machine coordinate system and the workpiece coordinate system to understand exercise this block, how much free exercise and so on;
7) register and buffer display: You can see the contents of the block being executed each state command and the next block.
8) main programs and subprograms Show: Learn being executed block specific content.
9) The dialogue display (Custom): Learn the machine spindle speed of the current, the current cutting feed rate, spindle cutting feed per revolution, spindle load and each cutting stroke current axle load Cutting feed per spindle revolution Tool to calculate the corresponding each edge Cutting capacity;
10) cut into the knife again, the run to the surface of the tool at 30 ~50mm, the feed must be kept at a low speed, verify the remaining axis coordinate value and X, Y-axis coordinate values are consistent with the pattern;
11) requirements for some test tool knife, a "progressive" approach. For example, boring, boring and short length can first try, after passing, then drilling the entire length. Use the tool radius compensation tool data can be descending, while trimming modify test;
12) trial cutting and machining, tool change, after aids, must re-measure the tool length and modify good tool offsets and tool offset number;
13) should be indicated by the cursor position to retrieve note is reasonable, accurate, and observe the direction of movement of the machine tool and the coordinate is correct;
After 14) changes in procedures to amend section must be carefully calculated and carefully check;
15) hand feed and manual continuous feed operation, you must check the position of the various switches chosen is correct, clarify the positive and negative directions, look for buttons and set the feed rate, or pulse rate, and then to operation.
