Spindle clamp Speed Setting:-Function and purpose:- The code G50 can be used to set the maximum and minimum spindle speeds at addresses S and Q, respectively.Programming Format:- G50 S__ Q __ R__ S = Maximum Spindle Speed Q =
Feed Rate
Feed RateFeed rate is the velocity at which the cutter is fed, that is, advanced against the work piece. It is expressed in units of distance per revolution for turning and boring (typically inches per revolution [ipr] or millimeters per revolution). It can be expressed thus for milling also, but it is often expressed in units of distance per time for milling (typically inches per minute [ipm] or millimeters per minute), with considerations of how many teeth (or flutes) the cutter has then determining what that means for each tooth.Feed rate is dependent on the:§

Constant Surface Speed Control On-Off
Constant Surface Speed Control On/Off: G96/G97Function and Purpose:- This function controls automatically the spindle speed as the coordinates are changed during cutting in diametric direction so as to execute cutting by keeping constant the relative speed between tool tip and work piece.Programming Format:- G96 S__ P__ R__ ; Constant Surface Speed Control On S =

Spindle Functions
Spindle function:- When the S5-digit function is added, this function must be set using the numerical command of five digits preceding an S code (0 to 99999) and for other case, two digits proceeding by an S code is used. S command binary outputs must be selected at this time.By designating a 5-digit number following the S code, this function enable the appropriates gear signals, voltages corresponding to the commanded spindle (rpm) and start signals to be output.

Define M code for Mazak machine , Okuma, Fanuc , Cincinnati, all control

Miscellaneous functions:- Miscellaneous functions, which are also referred to as M-code functions, give spindle forward /backward rotation and stop commands, coolant on/off commands and other auxiliary commands to the NC machine. For the NC unit, these functions must be selected using M3-digit data. Up to four sets of M3-digit data can be included in the block.Example:- G00 X__ M__ M__ M___ M___ ; &nb

How to make Thread Program In G32 Fanuc Machine

Thread Programming : - (G32) Function and purpose:- The G32 command control the federate of the tool in synchronization with the spindle rotation and so this enables both the straight and scrolled thread cutting of constant leads and the continuous thread cutting. Detailed Description:-1. Constant surfac
