First, the general rule of the tool path.

Opening thickness: under the maximum load of the machine tool, in most cases should choose the largest possible knife, the largest possible feed, as fast as possible. In the case of the same tool, the feed rate is inversely proportional antminer s19 pro for saleto the feed rate. In general, the load of the machine is not a problem, the principle of tool selection depends mainly on the two-dimensional angle of the product, the three-dimensional arc is too small to be considered. After selecting the tool, the tool length will be determined, the principle is that the tool is longer than the machining depth, and the large workpiece should be considered whether there is an overload chuck.

Light tool: The purpose of the light tool is to meet the requirements of the surface finish of the workpiece and to give an appropriate margin. Again, the light tool is as large as possible and as fast as possible, because the precision tool takes longer time with the most appropriate feed. At the same feed, the larger the lateral feed, the faster the cutting speed. The amount of feed for curved surface is related to the finish after processing, the feed size is related to the shape of the surface, leaving the smallest margin, the largest tool used, the fastest speed, and the appropriate amount of feed.

Second, the clamping method.

1. All clamping is horizontal long and vertical short.

2, vise clamping: clamping height development should not be less than 10 millimeters, in the process of machining the workpiece must be carried out to specify the clamping height and processing technology height. Processing enterprise height should be higher than the vise plane about 5 mm, the purpose is to ensure that students firmness, and at the same time in order cnc machining manufacturernot to hurt the vise. This kind of clamping is a general clamping, clamping height related also with the size of the workpiece as well as related, the larger the workpiece, the clamping height proposed a corresponding increase in risk.

3, pressure plate clamping: pressure plate with a code bar fixed on the table, the workpiece with screws locked in the pressure plate, suitable for clamping height is not enough, the processing force of the workpiece, the general effect of medium and large workpiece.

Code iron clamping: When the workpiece is large, the clamping height is not enough, and does not allow locking at the bottom of the screwdriver, and then clamping with a code iron. This clamping requires a second clamping, first code the four corners, processing other parts, and then code the four sides, processing the four corners. Do not let the workpiece loose during the second clamping, code first and then loosen. You can also code two sides first and process the other two sides.

5. tool clamping: diameter greater than 10mm, clamping length of not less than 30mm; diameter of 10mm or less, clamping length of not less than 20mm. tool clamping to be firm, it is strictly prohibited to hit the tool, directly into the workpiece.
