在具有间隙补偿功能的线切割机床上加工模具,单边间隙只要在△R所能寄存的范围内,编制一条凸模(或凹模)程序,就能加工出凹模(或凸模)、导压板、固定板。但当要求的间隙量超过△R时,是否也能只编一条程序加工一付模具呢? 设偏移量为△X(根据偏移情况不同,△X可大于或小于零),控制台在作偏移运算后,X寄存器的最终数值为两部分值之和,即X+△X,而△X根据上述过程可以用一个数学表达式来表示:△X=(X·△R)/R。从这个式子中我们可以看到,若分子、分母同时缩小n倍,其值是不
In the gap compensation with the function of wire cutting machine tool processing, as long as the unilateral clearance △ R can be stored in the range, the preparation of a punch (or die) program, you can process the die (or punch) Pressure plate, fixed plate. But when the required amount of clearance exceeds △ R, can we only make a program to process a pair of mold? Set the offset △ X (depending on the offset, △ X can be greater than or less than zero), the console in After the offset operation, the final value of the X register is the sum of the two parts, X + ΔX, and ΔX can be expressed by a mathematical expression according to the above process: ΔX = (X · ΔR) / R. From this formula we can see that if the numerator and denominator are reduced n times at the same time, the value is not
