A tool holder is the part that connects the cutting tool to the machine spindle. Get the holder right and the cutter runs concentric, rigid, and repeatable. Get it wrong and you chase runout, chatter, and scrapped parts all shift. Holders are not interchangeable across machines, because the mounting interface has to match the spindle [...]
Tool holder care and maintenance is of vital importance (especially when working with CNC machines) for many reasons! A rule of thumb to live by when working with CNC Machines is that an inspection of the toolholder and spindle should follow every use. This inspection should include disassembling the entirety of the toolholder and cleaning [...]
Every practice of compensation has to do with offsets (especially in regards to CNC offsets)! One can consider CNC offsets as memories on an electronic calculator. If your calculator has memory, you can store a constant value to each memory for use throughout a calculation. This keeps one from having to enter the number over [...]
Incremental system. Absolute system. Most controls on machine tools capable of handling both by altering code between G90 (absolute) and G91 (incremental) commands. All considerations to this point accept that the absolute mode of programming is used. The CNC word used to refer to the absolute mode is G90. In absolute mode, the [...]
CNC cutting tools can be divided into two main groups: traditional tools and modular tools. Modular tools are the tools of progress. The chief benefits of modular tools include reducing tool modification downtime, developing production and processing time, speeding up tool alteration and installation time, reducing the cost of small batch production, and developing the [...]
Place a few machine operators together in a room, ask them to discuss the pros and cons of a manual lathe as opposed to CNC lathe machining, and then close the door. What you will discover and hear is an intense discussion and much debate about which one is better! If one doesn’t come back [...]
A CNC user must be familiar with the makeup of the CNC machine tool being applied. Despite the fact that this may sound like a straightforward declaration, a CNC user must be able to observe the machine from two dissimilar viewpoints. Want to know more about CNC? Read in our blog over here. Many kinds [...]
The most rudimentary function of any core of CNC machine is automatic, accurate, and steady motion control. Rather than applying totally mechanical devices, as is obligatory on most conventional machine tools, CNC machines let you control motion in a groundbreaking manner. All methods of CNC equipment have two or more ways of motion, called axes. [...]
Hurco Training Class Room Almost all present CNC program controls use a word address arrangement for programming. The only exclusions to this are certain conversational controls. By the word address format, we indicate that the CNC program is made of sentence-like commands. Each command is fabricated of CNC words. Each CNC word has [...]
Want to understand more about interpolation? Say, for example, you wish to move only one linear axis in a command. Say you request to move the X axis to a location one inch to the right of program zero. In this circumstance, the command X1 would be used (assuming the total mode is instated). The [...]
