M06 also turns the coolant off if it is flowing. The work table should be positioned so that the tools can be removed and replaced in the spindle nose without interference from the work or vice. To provide this facility the machine table has to be moved away from the operator towards the left and the rear of the machine. This will also enable the operator to be able to reach for the tool without having to lean over the work. To determine the programmed coordinates of a safe position for tool changing it is necessary to consider the position of the work on the work table. With reference to Figure , the machine setting point is at machine coordinates of X175 and Y110. there is a maximum possible movement in the direction required of 300175=325 ㎜ on the X axis and 110 ㎜on the Y axis. To provide clearance to prevent the override microswitches being activated, it is remended that the maximum possible movement should not be programmed. The coordinates chosen for the tool change are X 300 and Y – will position the table so that there will be clearances of 25 and 10 ㎜ respectively on the X and Y axes to the microswitches. For a tool change the machine table will move so that the position of the centre of the spindle relative to the machine table will be as shown in Figure . On machines which have automatic tool changing facilities it may not be necessary to calculate the coordinates for tool changing. The control system may automatically position the tool spindle at the correct position ready for the tool transfer mechanism when a tool change is programmed. Where it is necessary to calculate the coordinates it is essential that the spindle head is moved so that there is adequate clearance for the transfer mechanism to operate without interference. The first ponent will be placed in the vice when the machine is under manual control during the setting up of the machine . when the machine is under program control, new work blanks will replace the finished workplace at the end of all the machineing operations. To provide sufficient space to carry out the work change, the machine table should be moved away from the tool in the spindle and towards the front of the machine or to a position nearest and convenient to the operator. This gives the operator’ s hands from the tools. The swarf would have to be cleared away before the vice jaws and opened. Obviously for safe working practice the main tool spindle would be programmed to stop rotating in the last block before work changing. The machine setting point is X 175 and Y 110, and therefore the maximum possible movement of the machine table towards the right and front of the machine is – 175 ㎜ on the X axis, and 300100=190 ㎜ on the Y allow some latitude in the positioning of the vice on the machine table and to provide clearance to prevent the override microswitches being activated, the program coordinates selected for a safe position for changing the work are X – 150 and Y 170. The position of the centre of the spindle relative to the machine table at work changing is shown in Figure . ? Setting milling and drilling tools If the machine has a tool storage facility from which tools can be automatically selected, the tools have to be placed in the correct numbered location as allocated by the programmer. If the tools have a builtin identification which can be resd by the sensing mechanism, the loading of the tools in specific locations is not so important. See Chapter 3 for information on tool identification. If the machine has a tool turrent the tools have to be mounted in the correct station. Tool setting on machineing centres using multipoint tools is mainly establishishing the Z datum as it is not possible to change the diameter of milling cutters and drills. ? Setting the tools to the Z satum The tools used will be of different lengths, and every tool has to be set so that its programmed movement takes place at the relevant part of the work. This requires that when the point or end of each tool is in contact with that part of the work or is at th
