CNC turning cycle programming is an integral part of the manufacturing industry. It facilitates the production of intricate designs with commendable accuracy, precision and repetitiveness. Therefore, understanding the basics and mastering the art of this ingenious technique can substantially amplify the growth trajectory of one's manufacturing career.
The Foundation Stage - Understanding the Basics
Let's begin by familiarizing ourselves with the concept of Computer Numerical Control (CNC) turning. At its core, turning involves revolving the workpiece while the state-of-the-art cutting tool shapes it. The spectacular precision and repetitiveness of CNC turning is achieved by the computer control of machine tool movement in accordance with the pre-programmed software instructions.
Now, let's delve into the diverse types of turning cycle programming. Primarily, they include rough turning, finish turning, thread cutting, and grooving, each with a unique set of operational methods and programming quirks.
Stage 1: Rough Turning
Rough turning, as the name suggests, is characterized by removing large amounts of materials quickly but with less accuracy. It＊s the first step towards shaping the workpiece. The cycle parameters for rough turning are normally programmed via the code G71 in the majority of CNC machines, followed by cycle parameters such as finishing allowance, depth of cut, and pecking depth.
Stage 2: Finish Turning
After the workpiece has been rough turned, it undergoes finish turning, where fine cuts are made to achieve the final dimensions with high precision. The finish turning cycle is typically programmed using the code G70 followed by a sequence number that calls the rough turning cycle...
