在數(shù)控車床加工中，加工路線的確定一般要遵循以下幾方面原則。

①應能保證被加工工件的精度和表面粗糙度。

②使加工路線比較短，減少空行程時間，提高加工效率。

③盡量簡化數(shù)值計算的工作量，簡化加工程序。

④對于某些重復使用的程序，應使用子程序。

In NC lathe processing, the determination of the processing route generally follows the following principles.
1 It should be able to guarantee the accuracy and surface roughness of the workpiece being processed.
Make the processing route the shortest, reduce the empty travel time and improve the processing efficiency.
3 Try to simplify the workload of numerical calculations and simplify the processing process.
For some reusable procedures, subroutines should be used.
